I am after information on implementing a linux-based alternative for SBS/NT. (Sorry for the partial cross-posting!) My main goal is central authentication(Via pam->mysql) of all services (Samba/Mail(QMail)/IMAP(Courier)/LDAP?/Ical?(Calendar/Contact Sharing - Or considering something like phpGroupware if Ical doesn't cut the mustard?)), and hopefully centralised administration? I have implemented Samba with pam_mysql and it works nicely! Has anyone implemented anything similar to this? Experiences in doing so? Is LDAP necessary (Benefits?) I would really appreciate any feedback! Thanks in advance. Regards, Michael -------------- next part -------------- HTML attachment scrubbed and removed
