[Samba] samba, ldap, kerberos

[Pramathesh Ambasta]

Though I am not new to samba, I am new to this so will really appreciate 
guidance. If I want to implement a single sign on scheme using openldap 
and kerberos on a linux server, how can samba be integrated into this 
scheme? As far as I can understand from the docs, the discussions on 
samba and kerberos deal with samba integration into an active directory 
domain. Does that mean that what I am talking about cannot be done?

Grateful for help
