See section 8.2 for more details.
The cn=NextFreeUnixId,dc=idealx,dc=org entry is only used to defined the next uidNumber and gidNumber available for creating new users and groups. The default values for those numbers are 1000. You can change it with the -u and -g option. For example, if you want the first available value for uidNumber and gidNumber to be set to 1500, you can use the following command :
smbldap-populate -u 1550 -g 1500
4.2 User management
4.2.1 Adding a user
To add a user, use the smbldap-useradd script. Available options are summarized in the table 2. If applicable, default values are mentionned in the third column. Any string beginning with a $ symbol refers to a parameter defined in the /etc/opt/IDEALX/smbldap-tools/smbldap.conf configuration file.For example, if you want to add a user named user_admin and who :
option definition example default value -a create a Windows account. Otherwise, only a Posix account is created -w create a Windows Workstation account -i create an interdomain trust account. See section 4.4 for more details -u set a uid value -u 1003 first uid available -g set a gid value -g 1003 first gid available -G add the new account to one or several supplementary groups (comma-separated) -G 512,550 -d set the home directory -d /var/user $userHomePrefix/user -s set the login shell -s /bin/ksh $userLoginShell -c set the user gecos -c "admin user" $userGecos -m creates user's home directory and copies /etc/skel into it -k set the skeleton dir (with -m) -k /etc/skel2 $skeletonDir -P ends by invoking smbldap-passwd to set the user's password -A user can change password ? 0 if no, 1 if yes -A 1 -B user must change password at first session ? 0 if no, 1 if yes -B 1 -C set the samba home share -C \\PDC\homes $userSmbHome -D set a letter associated with the home share -D H: $userHomeDrive -E set DOS script to execute on login -E common.bat $userScript -F set the profile directory -F \\PDC\profiles\user $userProfile -H set the samba account control bits like'[NDHTUMWSLKI]' -H [X] -N set the canonical name of the user -S set the surname of the user -M local mailAddress (comma seperated) -M testuser,aliasuser -T forward mail address (comma seperated) -T testuser@domain.org
Table 2: Options available to the smbldap-useradd script
- is a windows user
- must belong to the group of gid=512 ('Domain Admins' group)
- has a home directory
- does not have a login shell
- has a homeDirectory set to /dev/null
- does not have a roaming profile
- and for whom we want to set a first login password
smbldap-useradd -a -G 512 -m -s /bin/false -d /dev/null -F "" -P user_admin
4.2.2 Removing a user
To remove a user account, use the smbldap-userdel script. Available options areFor example, if you want to remove the user1 account from the LDAP directory, and if you also want to delete his home directory, use the following command :
option definition -r remove home directory -R remove home directory interactively
Table 3: Option available to the smbldap-userdel script
smbldap-userdel -r user1Note: '-r' is dangerous as it may delete precious and unbackuped data, please be careful.
4.2.3 Modifying a user
To modify a user account, use the smbldap-usermod script. Availables options are listed in the table 4.You can also use the smbldap-userinfo script to update user's information. This script can also be used by users themselves to update their own informations listed in the tables 5 (adequats ACL must be set in the directory server). Available options are :
option definition example -c set the user gecos -c "admin user" -d set the home directory -d /var/user -u set a uid value -u 1003 -g set a gid value -g 1003 -G add the new account to one or several supplementary groups (comma-separated) -G 512,550 -G -512,550 -G +512,550 -s set the login shell -s /bin/ksh -N set the canonical name of the user -S set the surname of the user -P ends by invoking smbldap-passwd to set the user's password -a add sambaSAMAccount objectclass -e set an expiration date for the password (format: YYYY-MM-DD HH:MM:SS) -A user can change password ? 0 if no, 1 if yes -A 1 -B user must change password at first session ? 0 if no, 1 if yes -B 1 -C set the samba home share -C \\PDC\homes -C "" -D set a letter associated with the home share -D H: -D "" -E set DOS script to execute on login -E common.bat -E "" -F set the profile directory -F \\PDC\profiles\user -F "" -H set the samba account control bits like'[NDHTUMWSLKI]' -H [X] -I disable a user account -I 1 -J enable a user -J 1 -M local mailAddress (comma seperated) -M testuser,aliasuser -T forward mail address (comma seperated) -T testuser@domain.org
Table 4: Options available to the smbldap-usermod script
option definition example -f set the full name's user -f MyName -r set the room number -r 99 -w set the work phone number -w 111111111 -h set the home phone number -h 222222222 -o set other information (in gecos definition) -o "second stage" -s set the default bash -s /bin/ksh
Table 5: Options available to the smbldap-userinfo script
4.3 Group management
4.3.1 Adding a group
To add a new group in the LDAP directory, use the smbldap-groupadd script. Available options are listed in the table 6.
option definition example -a add automatic group mapping entry -g gid set the gidNumer for this group to gid -g 1002 -o gidNumber is not unique -r group-rid set the rid of the group to group-rid -r 1002 -s group-sid set the sid of the group to group-sid -s S-1-5-21-3703471949-3718591838-2324585696-1002 -t group-type set the sambaGroupType to group-type -t 2 -p print the gidNumber to stdout
Table 6: Options available for the smbldap-groupadd script
4.3.2 Removing a group
To remove the group named group1, just use the following command :smbldap-userdel group1
4.4 Adding a interdomain trust account
To add an interdomain trust account to the primary controller trust-pdc, use the -i option of smbldap-useradd as follows :[root@etoile root]# smbldap-useradd -i trust-pdc New password : ******* Retype new password : *******The script will terminate asking for a password for this trust account. The account will be created in the directory branch where all computer accounts are stored (ou=Computers by default). The only two particularities of this account are that you are setting a password for this account, and the flags of this account are [I ].
5 Samba and the smbldap-tools scripts
5.1 General configuration
Samba can be configured to use the smbldap-tools scripts. This allows administrators to add, delete or modify user and group accounts for Microsoft Windows operating systems using, for example, User Manager utility under MS-Windows. To enable the use of this utility, samba needs to be configured correctly. The smb.conf configuration file must contain the following directives :ldap delete dn = Yes add user script = /usr/local/sbin/smbldap-useradd -m "%u" add machine script = /usr/local/sbin/smbldap-useradd -w "%u" add group script = /usr/local/sbin/smbldap-groupadd -p "%g" add user to group script = /usr/local/sbin/smbldap-groupmod -m "%u" "%g" delete user from group script = /usr/local/sbin/smbldap-groupmod -x "%u" "%g" set primary group script = /usr/local/sbin/smbldap-usermod -g "%g" "%u"Remark: the two directives delete user script et delete group script can also be used. However, an error message can appear in User Manager even if the operations actually succeed. If you want to enable this behaviour, you need to add
delete user script = /usr/local/sbin/smbldap-userdel "%u" delete group script = /usr/local/sbin/smbldap-groupdel "%g"
5.2 Migrating an NT4 PDC to Samba3
The account migration procedure becomes really simple when samba is configured to use the smbldap-tools. Samba configuration (smb.conf file) must contain the directive defined above to properly call the script for managing users, groups and computer accounts. The migration process is outlined in the chapter 30 of the samba howto http://sambafr.idealx.org/samba/docs/man/Samba-HOWTO-Collection/NT4Migration.html.6 Frequently Asked Questions
6.1 How can i use old released uidNumber and gidNumber ?
There are two way to do this :-
modify the cn=NextFreeUnixId,dc=idealx,dc=org and
change the uidNumber and/or gidNumber value. This
must be done manually. For example, if you want to use all available
uidNumber and gidNumber higher then 1500, you need to create a
update-NextFreeUnixId.ldif file containing :
dn: cn=NextFreeUnixId,dc=idealx,dc=org changetype: modify uidNumber: 1500 gidNumber: 1500
and then update the directory :ldapmodify -x -D "cn=Manager,dc=idealx,dc=org" -w secret -f update-NextFreeUnixId.ldif
- use the -u or -g option to the script you need to set the value you want to use
6.2 I always have this error: "Can't locate IO/Socket/SSL.pm"
This happens when you want to use a certificate. In this case, you need to install the IO-Socket-SSL Perl module.6.3 I can't initialize the directory with smbldap-populate
When I want to initialize the directory using the smbldap-populate script, I get[root@slave sbin]# smbldap-populate.pl Using builtin directory structure adding new entry: dc=IDEALX,dc=COM Can't call method "code" without a package or object reference at /usr/local/sbin/smbldap-populate.pl line 270, <GEN1> line 2.Answer: check the TLS configuration
-
if you don't want to use TLS support, set the /etc/opt/IDEALX/smbldap-tools/smbldap.conf file
with
ldapSSL="0"
- if you want TLS support, set the /etc/opt/IDEALX/smbldap-tools/smbldap.conf file with
ldapSSL="1"
and check that the directory server is configured to accept TLS connections.
6.4 I can't join the domain with the root account
- check that the root account has the sambaSamAccount objectclass
- check that the directive add machine script is present and configured
6.5 I have the sambaSamAccount but i can't logged in
Check that the sambaPwdLastSet attribute is not null (equal to 0)6.6 I want to create machine account on the fly, but it does not works or I must do it twice
- The script defined with the add machine script must not add the sambaSAMAccount objectclass of the machine account. The script must only add the Posix machine account. Samba will add the sambaSAMAccount when joining the domain.
- Check that the add machine script is present in samba configuration file.
6.7 I can't manage the Oracle Internet Database
If you have an error message like :Function Not Implemented at /usr/local/sbin/smbldap_tools.pm line 187. Function Not Implemented at /usr/local/sbin/smbldap_tools.pm line 627.For Oracle Database, all attributes that will be resquested to the directory must be indexed. Add a new index for samba attributes and make sure that the following attributes are also indexed : uidNumber, gidNumber, memberUid, homedirectory, description, userPassword ...
6.8 The directive passwd program = /usr/local/sbin/smbldap-passwd -u %u is not called, or i got a error message when changing the password from windows
The directive is called if you also set unix password sync = Yes. Notes:- if you use OpenLDAP, none of those two options are needed. You just need ldap passwd sync = Yes.
- the script called here must only update the userPassword attribute. This is the reason of the -u option. Samba passwords will be updated by samba itself.
- the passwd chat directive must match what is prompted when using the smbldap-passwd command
6.9 New computers account can't be set in ou=computers
This is a known samba bug. There's a workarround: look at http://marc.theaimsgroup.com/?l=samba&m=108439612826440&w=26.10 I can join the domain, but i can't log on
look at section 6.96.11 I can't create a user with smbldap-useradd
When creating a new user account I get the following error message:/usr/local/sbin/smbldap-useradd.pl: unknown group SID not set for unix group 513Answer:
- is nss_ldap correctly configured ?
- is the default group's users mapped to the 'Domain Users' NT group ?
net groupmap add rid=513 unixgroup="Domain Users" ntgroup="Domain Users"
6.12 smbldap-useradd: Can't call method "get_value" on an undefined value at /usr/local/sbin/smbldap-useradd line 154
- does the default group defined in smbldap.conf exist (defaultUserGid="513") ?
- does the NT "Domain Users" group mapped to a unix group of rid 513 (see option -r of smbldap-groupadd and smbldap-groupmod to set a rid) ?
6.13 Typical errors on creating a new user or a new group
-
i've got the following error:
Could not find base dn, to get next uidNumber at /usr/local/sbin//smbldap_tools.pm line 909
-
you do not have created the object to defined the next uidNumber and gidNumber available.
- for version 0.8.7 : you can just run the smbldap-populate script that will update the sambaDomain entry to store those informations
- for version before 0.8.7 :
You have updated the smbldap-tools to version 0.8.5 or newer.
You have to do this manually. Create an file called add.ldif and containing
dn: cn=NextFreeUnixId,dc=idealx,dc=org objectClass: inetOrgPerson objectClass: sambaUnixIdPool uidNumber: 1000 gidNumber: 1000 cn: NextFreeUnixId sn: NextFreeUnixId
and then add the object with the ldapadd utility:$ ldapadd -x -D "cn=Manager,dc=idealx,dc=org" -w secret -f add.ldif
Here, 1000 is the first available value for uidNumber and gidNumber (of course, if this value is already used by a user or a group, the first available after 1000 will be used).
- The error also appear when there is a need for TLS (ldapTLS=1 in smbldap.conf) and something is wrong with certificate naming or path settings.
-
you do not have created the object to defined the next uidNumber and gidNumber available.
- i've got the following error:
Use of uninitialized value in string at /usr/local/sbin//smbldap\_tools.pm line 914. Error: No DN specified at /usr/local/sbin//smbldap\_tools.pm line 919
You have not updated the configuration file to defined the object where are sotred the next uidNumber and gidNumber available. In our example, you have to add a nex entry in /etc/opt/IDEALX/smbldap-tools/smbldap.conf containing :# Where to store next uidNumber and gidNumber available sambaUnixIdPooldn="cn=NextFreeUnixId,${suffix}"btw, a new option is now available too: the domain to append to users. You can add to the configuration file the following lines:# Domain appended to the users "mail"-attribute # when smbldap-useradd -M is used mailDomain="idealx.com"
- i've got the following error:
Use of uninitialized value in concatenation (.) or string at /usr/local/sbin/smbldap-useradd line 183. Use of uninitialized value in substitution (s///) at /usr/local/sbin/smbldap-useradd line 185. Use of uninitialized value in string at /usr/local/sbin/smbldap-useradd line 264. failed to add entry: homedirectory: value #0 invalid per syntax at /usr/local/sbin/smbldap-useradd line 280. userHomeDirectory=User "jto" already member of the group "513". failed to add entry: No such object at /usr/local/sbin/smbldap-useradd line 382.
you have to change the variable name userHomePrefix to userHome in /etc/opt/IDEALX/smbldap-tools/smbldap.conf
- i've got the following error:
failed to add entry: referral missing at /usr/local/sbin/smbldap-useradd line 279, <DATA> line 283.
you have to update the configuration file that defined users, groups and computers dn. Those parameters must not be relative to the suffix parameter. A typical configuration look like this :usersdn="ou=Users,${suffix}" computersdn="ou=Computers,${suffix}" groupsdn="ou=Groups,${suffix}"
- i've got the following error:
erreur LDAP: Can't contact master ldap server (IO::Socket::INET: Bad protocol 'tcp') at /usr/local/sbin//smbldap_tools.pm line 153.
remove ldap from /etc/nsswitch.conf for services list of possible check. For example, if your ldap directory is not configured to give services information, you must haveservices files
and notservices: ldap [NOTFOUND=return] files

8.2 Changing the administrative account (ldap admin dn in smb.conf file)
If you don't want to use the cn=Manager,dc=idealx,dc=com account anymore, you can create a dedicated account for Samba and the smbldap-tools scripts. To do this, create an account named samba as follows (see section 4.2.1 for a more detailed syntax) :smbldap-useradd -s /bin/false -d /dev/null -P sambaThis command will ask you to set a password for this account. Let's set it to samba for this example. You then need to modify configuration files:
-
file /etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf
slaveDN="uid=samba,ou=Users,dc=idealx,dc=com" slavePw="samba" masterDN="uid=samba,ou=Users,dc=idealx,dc=com" masterPw="samba" - file /etc/samba/smb.conf
ldap admin dn = uid=samba,ou=Users,dc=idealx,dc=comdon't forget to also set the samba account password in secrets.tdb file :smbpasswd -w samba
- file /etc/openldap/slapd.conf: give to the
samba user permissions to modify some attributes: this
user needs to be able to modify all the samba attributes and some
others (uidNumber, gidNumber ...) :
# users can authenticate and change their password access to attrs=userPassword,sambaNTPassword,sambaLMPassword,sambaPwdLastSet,sambaPwdMustChange by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by self write by anonymous auth by * none # some attributes need to be readable anonymously so that 'id user' can answer correctly access to attrs=objectClass,entry,gecos,homeDirectory,uid,uidNumber,gidNumber,cn,memberUid by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by * read # somme attributes can be writable by users themselves access to attrs=description,telephoneNumber by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by self write by * read # some attributes need to be writable for samba access to attrs=cn,sambaLMPassword,sambaNTPassword,sambaPwdLastSet,sambaLogonTime,sambaLogoffTime,sambaKickoffTime,sambaPwdCanChange,sambaPwdMustChange,sambaAcctFlags,displayName,sambaHomePath,sambaHomeDrive,sambaLogonScript,sambaProfilePath,description,sambaUserWorkstations,sambaPrimaryGroupSID,sambaDomainName,sambaSID,sambaGroupType,sambaNextRid,sambaNextGroupRid,sambaNextUserRid,sambaAlgorithmicRidBase by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by self read by * none # samba need to be able to create the samba domain account access to dn.base="dc=idealx,dc=com" by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by * none # samba need to be able to create new users account access to dn="ou=Users,dc=idealx,dc=com" by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by * none # samba need to be able to create new groups account access to dn="ou=Groups,dc=idealx,dc=com" by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by * none # samba need to be able to create new computers account access to dn="ou=Computers,dc=idealx,dc=com" by dn="uid=samba,ou=Users,dc=idealx,dc=com" write by * none # this can be omitted but we leave it: there could be other branch # in the directory access to * by self read by * none
8.3 known bugs
- Option -B (user must change password) of smbldap-useradd does not have effect: when smbldap-passwd script is called, sambaPwdMustChange attribute is rewrite.
