Hello, After looking into Samba 4's offerings, I am curious about the extent to which they might render other daemons redundant. I read that there were some difficulties with respect to OpenLDAP that ultimately resulted in the inclusion of an internal LDAP server. Now Heimdal Kerberos V appears to be integrated. To what extent can these embedded versions replace stand-alone OpenLDAP or Heimdal Kerberos systems, and to what extend should they? How flexible is Samba 4's LDAP server? In particular, if I used Samba 4 for Windows authentication, is there any reason that I should maintain a separate Kerberos and LDAP server for my Linux clients if I wanted to migrate authentication from some other directory via PAM and NSS? As an aside, I can appreciate the integration of these things, but is this kitchen sink approach necessary when interoperability between the separate packages could be increased? Best, Matt
