Access Control using NIS

[Jack Bates <jdb813@telus.net>]

I have been over the OpenLDAP Administrator's Guide, Linux LDAP HOWTO, 
and Cyrus SASL for System Administrators, but am still trying to wrap 
my head around authentication. I'm only just setting up an LDAP server, 
so I don't want to store authentication information using LDAP, yet. 
Users currently login using NIS, so I would like to setup access 
control on the LDAP directory using NIS. I can't figure out if this can 
be done using the "simple" authentication method, or whether I must use 
SASL. If I must use SASL, I can't figure out where to configure the 
appropriate SASL method, or in what format I supply usernames and 
passwords to ldapsearch etc. Clarification would be much appreciated.

Thanks,

Jack
