I thought I had seen tools that can proxy LDAP services to multiple 
backends, with one of them being AD but at the time it seemed too 
complicated so I set up pam_smb and mod_auth_pam in apache (and set up 
apache to not require account info).  That lets me add local accounts to 
a machine for the people who either need login-type services or aren't 
in AD and still accept passwords that are in AD.  But, it has to be 
repeated per machine and I don't have java web services working with it. 
  What I'd like to have is an LDAP server or even a separate AD server 
to manage extra users and then a proxy service that combines the logins 
from both sources for any number of clients.  Basically I want to trust 
both authentication sources, but not add mine to the main AD or have it 
trust mine, and I want it in a way that apache, java, etc. already 
understand, besides being usable for login service.
