That's the problem - PAM stacks methods nicely.  Most other things can 
use multiples too, but you have to configure each app in weird ways to 
do it.  That's why I think configuring PAM and apps that don't use PAM 
to use LDAP would be the cleanest approach, then configure the LDAP 
server side to merge the accounts I want - or make it look that way by 
proxying.

It's really tomcat under the covers on the server side (so probably 
acecgi like opennms).  The code is all available in the community 
edition - but it is enough of a monster that you probably would need the 
support if you needed to do more than a few reports, which is all I'm 
doing so far.  It's probably overkill but I really hate doing report 
layout work manually and it has a nice interactive design tool that 
publishes the runtime to the web server where it can generate html, pdf, 
or a spreadsheet download.

Machines using smb auth don't have to join the domain - and it doesn't 
need any special support.  For apache, mod_auth_pam works, but isn't a 
stock centos module.  I think you are supposed to be able to use 
mod_auth_sasl with pam these days but I haven't tried to convert yet.

So far an occasional 'addusr somebody; passwd somebody' has been easier 
than setting up a network database that I can trust.

I think that's near infinite - especially if you try to set something up 
for future use.

So far there aren't that many machines or users that need exceptions 
from what smb_auth provides - but I'd probably try to migrate more stuff 
currently on windows boxes if everything was seamless.
