postfix w/pam

[Curtis Vaughan]

Can anyone tell me whether I have to install/build postfix w/pam 
support (if I want it to use pam). Or can I just do a make install of 
postfix, as well as of pam_ldap and nss_ldap, edit the appropriate 
files in /etc/pam.d/ and it should work?

I have installed map_ldap and nss_ldap and have edited:
/usr/local/etc/ldap.conf
/etc/nsswitch.conf
files within /etc/pam.d, particularly /etc/pam.d/ldap, ./imap and 
./sshd and ./su
/usr/local/etc/nss_ldap.conf

But nonetheless it's not working with postfix (smtp) or with 
courier-imap (ssh works fine with pam).
