We currently are in the process of migrating our boxes from NT/2000 to a Samba Backend with Ldap.
Our first part of migration is completed. We've moved over to a samba box with LDAP using the PAM_SMBPASS to authenticate. We also created an LDAP backend to handle passwords and login authentication.
Problem: We need to keep PAM_SMBPASS and LDAP to integrate properly. Can Zimbra use the PAM_SMBPASS system on our external LDAP box to authenticate to Zimbra? We'd like it so that we use one login for everything.
