[Samba] samba with customized ldap backend

[Arun Gupta]

Sir,


  No AD, that's some NT4 domain.
Yes, it has no AD

- No Winbind because Winbind is using samacccountname as user login and not UID.
--> Not configured

> - Issue happens on Linux or UNIX clients.
On both client


I am using sssd and pam_ldap for user retrival and modified 
pam_login_attribute (pam_ldap.conf file) to username instead of uid (by 
default value) so I am very well able to authenticate with many services like ssh, smtp 
auth etc but in sabma case it is trying to contact uid='numeric value' 
instead of username=test1.

I think somewhere in configuration, we may define username attribute 
instead of uid which is samba configured.

Regards,
Arun
