[Samba] Configuration of idmap_ldap "No backend defined"

Hi list,

I can't make idmap talk to my LDAP server. And I haven't found an
updated
howto.

Some entries from log.windbindd-imap:

Part of my smb.conf:
[global]
    ldap admin dn = cn=Manager,dc=example,dc=com
    ldap delete dn = Yes
    ldap group suffix = ou=Groups
    ldap idmap suffix = ou=Idmap
    ldap machine suffix = ou=Computers
    ldap passwd sync = yes
    ldap suffix = dc=example,dc=com
    ldap user suffix = ou=People
    ldap debug level = 1
    idmap config *:backend = ldap
    idmap config *:readonly = no
    idmap config *:range = 1000-1999999
    idmap config *:ldap_url=ldap://localhost
    idmap config *:ldap_base_dn = cn=Manager,dc=example,dc=com
    idmap config MYDOMAIN:backend = ldap
    idmap config MYDOMAIN:readonly = no
    idmap config MYDOMAIN:range = 1000-1999999
    idmap config MYDOMAIN:ldap_url=ldap://localhost
    idmap config MYDOMAIN:ldap_base_dn = cn=Manager,dc=example,dc=com
    idmap config MYDOMAIN:ldap_user_dn = cn=admin,ou=Idmap,dc=example,dc=com

I'm running samba 3.6.3 on FreeBSD 9.0-RELEASE and my LDAP server seems to
work otherwise. At least, I can do user authentication this way.

Of course, I can provide much more information from the logs and the
configuration files. I just don't know where to start. And any help would
be much appreciated.

Best regards,
Jon Theil Nielsen

[Samba] Configuration of idmap_ldap "No backend defined"

Hi,

please check your ldap configuration in your smb.conf file. At first verify that
your base-dn is really  "dc=example,dc=com". Than remove
"cn=Manager" from each option that contains "base_dn".

As usual, make sure that your LDAP server is set up correctly and that everthing
works fine. Than you can connect samba to your LDAP.

Cheers,

Christian

[Samba] Configuration of idmap_ldap "No backend defined"

Hi and thanks,

The base dn is not as shown. Might be some kind of paranoia...
I changed the smb.conf as suggested. Did not change any other file. Now my
log shows:

[2012/04/14 20:29:36.891125,  2] lib/smbldap.c:1018(smbldap_open_connection)
  smbldap_open_connection: connection opened
[2012/04/14 20:29:36.901600,  0] winbindd/idmap_ldap.c:192(verify_idpool)
  Multiple entries returned from (objectclass=sambaUnixIdPool) (base
=dc=example,dc=com)
[2012/04/14 20:29:36.901919,  1]
winbindd/idmap_ldap.c:516(idmap_ldap_db_init)
  idmap_ldap_db_init: failed to verify ID pool (NT_STATUS_UNSUCCESSFUL)
[2012/04/14 20:29:36.903646,  5]
winbindd/idmap_ldap.c:421(idmap_ldap_close_destructor)
  The connection to the LDAP server was closed
[2012/04/14 20:29:36.904039,  1] winbindd/idmap.c:249(idmap_init_domain)
  idmap initialization returned NT_STATUS_UNSUCCESSFUL

Regards,
Jon
