In our own research at UTA we found this to be true.  There are a handful of aspects that make AD problematic from the LDAP standpoint.  It is also problematic when you want to use it even for Authentication and Authorization of machines not running Windows.  While there are probably workarounds for everything, why not simply run software that works as expected and as dictated by RFC rather than spaghetti-code some workarounds?

For our central authentication and authorization, we us AD for Windows but we us Kerberos and OpenLDAP for everything else.
