Yes and no. Actually i do not want to have the whole AD domain. What i need is
to sync Nt passwords with unices ones. Currently, we have Unices
authenticating and getting accounts from an LDAP server. I would like to
minimize the changes for unices and do not want them to authenticate against
It seemed that Kerberos could have been the solution, but i am open to any

Yes, i know. I was wondering about using pgina (a replacement for msgina that
uses pam-like authentication) by adding a pam_krb5 module. This would
authenticate the Nt station against the Kerberos KDC and then let msgina get
the standard NT domain authentication against Samba PDC.
What i asked myself (and to you) was if there was no way to get NT Kerberos
credentials already acquired against the KDC to authenticate against PDC and
so avaoid re-authenticating on the NTLM manner, and thus avoid sending the
passord, even encrypted, on the network.
I am aware that it is not standard and so should not be implemented, but i was
wondering about any trick to do so.
The point is that i think i will have to implement the pam_krb5 module for
pgina if there is no contradiction with standard authentication. Or prehaps
someone has an experience to share about my password syncing problem ?
