[ldap] Expanding authentication and authorization in LDAP

[Matt Juszczak]

Hi all,

I'm familiar with ldap, but I'm not sure if this would be a question for 
this list, or for an ldap server setup specifically (such as openldap's 
list).

I'm looking to use LDAP for a project, but need a bit better 
authentication than just authenticating with a DN and a password.  I was 
hoping to use some sort of access list, or something similar.

Is this an LDAP protocol specific question (are the terms for 
authentication defined in the ldap protocol itself, and if so, what 
options do I have for authentication and authorizing LDAP server access?), 
or is this more for a specific server mailing list, such as openldap?

Thanks!
