mod_authz_ldap for CoSign

[Phil Pishioneri <pgp@xxxxxxx>]

We're trying to use mod_authz_ldap with the patches in the 
mod_authz_ldap-NOTES.txt file (Apache v1).  Actually, in the uMich 
version of the notes (mod_authz_ldap-NOTES-UMICH.txt), it says

> 4) edit your httpd.conf: IMPORTANT! mod_authz_ldap must be loaded *AFTER* mod_cosign, otherwise some very bad, bad things will happen. :)
>
> #this path will vary based on where you house your .so
> #mod_cosign must go first!
>     LoadModule cosign__module  libexec/mod_cosign.so
>     LoadModule authz_ldap_module  libexec/mod_authz_ldap.so
>   

When we do the config this way (along with the other directives), 
mod_cosign does not get called before mod_authz_ldap (the redirect for 
login never even happens on a fresh browser).

If we reverse the order, CoSign login does happen first, but 
mod_authz_ldap does not have a "user" set (references appear to be a 
null pointer).

Anyone have suggestions/seen similar problems?
