[Samba] Samba using pdb ldapsam fails upon startup

[Karsten Voigt]

Dear all,

I freshly installed a new smb-server that should act as file server with 
some smb-shares.

The pdc is a Windows 2008 r2 server.

My smb.conf is as follows:

[global]
         workgroup = agroup
         server string = ssmbserver
         #passdb backend = tdbsam
         map to guest = Bad User
         usershare allow guests = No
         security = domain
         wins support = No
         domain logons = No
         domain master = No
         # LDAP
         idmap backend = ldap:ldap://apdc.agroup.privat
         ldap suffix = DC=agroup,DC=privat
         ldap admin dn = CN=Administrator,CN=users,DC=agroup,DC=privat
         ldap user suffix = ou=Users
         ldap group suffix = ou=Groups
         ldap idmap suffix = ou=Idmap
         ldap machine suffix = ou=Machines
         ldap passwd sync = Yes
         ldap ssl = Off
         passdb backend = ldapsam:ldap://apdc.agroup.privat
         idmap gid = 1000-20000
         idmap uid = 1000-20000
         username level = 1
         realm = AGROUP.PRIVAT
         template homedir = /home/%D/%U
         winbind refresh tickets = yes
         password server = *
[homes]
[...]

If I try to start samba, the error message will be as follows:

-- Subject: Unit smb.service has failed

When I use passwd tdbsam, it will work fine, but I guess I use the 
NIS-accounts instead.

Thanks in advance,

Karsten
