Well if they offer the same PHP functions of course they can't be used  
at the same time - they export the same symbols. I'm a bit removed  
from my C programming, but that's the level this issue is at - way too  
late at the Horde level to do anything about it.

However, if php_auth.so (or is it pam_auth.so?) provides the same  
functionality (with the same arguments and semantics) that pam.so  
does, then we could check for either one. I'd be strongly against this  
if the only issue is that debian renames the library, btw - that's a  
horrible thing to do and Debian should fix that if that's the case.  
But if this is a new extension that's maintained - I seem to recall  
that the pam extension isn't maintained anymore - that's fine. Do you  
have a URL for the pam_auth extension?
