does sendmail work with ldap groups?

[Jay Christner <jaymc@goshen.edu>]

Hi,
  I'm in the process of migrating our userbase (~1500 users) from a
Netscape Messaging/Directory setup running on WindowsNT to
OpenLDAP/Sendmail/pop/IMAP/nss_ldap/pam_ldap running on RedHat Linux.  So
far I've gotten everything to work perfectly.  I can send mail, check
mail, etc with users only existing in the LDAP servers.  However one big
thing I'm missing at this point is groups.  In our existing Netscape
server we have lots of groupOfUniqueNames with uniquemembers in
them.  Netscape's mail server can use these as email groups, and there (I
think, though don't hold me on this) are restrictions you can put on
these groups that only members in the group can email to the group,
etc.  My questions is this: Will sendmail work with these groups (or
anyother groups stored in LDAP?
  
 We are using the default sendmail (at this point anyways) that came with
RedHat, in otherwords we have no special LDAP support compiled
in.  Sendmail currently works with nss_ldap and pam_ldap so it seems to be
working with LDAP just fine.  
Does anybody have any experience with this or suggestions?

If we can't get sendmail to use group stored in LDAP for email groups and
get some sort of access control on them, we'll be forced to use majordomo
or something like that for lists (which won't be near as nice).

Also the current groups work for authentication web based services via the
auth_ldap apache module, so the solution needs to work with that too.

Any thoughts?
