[NTLUG:Discuss] Enterprise PC Authentication

[chris.gamble@CPBINC.com]

I am looking for a way to authenticate a corporation of PC's using either
pam_ldap or pam_pgsql with the appropriate NSS libraries. The services
offered will be sendmail and some pop/imap server, and standard pc logins
for linux and windows (using samba for windows). 

I have been looking at ldap because I know that has been done at least a few
times before, but I almost prefer to try to stick to the postgres database
system since I know rdbms very well, whereas I do not know ldap at all. 

Anyone have any thoughts or suggestions they would like to share? Is
pam_pgsql a good option, etc?
