To All,
I am attempting to setup a server to use SSPI for mapping operating system 
users/groups to various postgres roles. In process I found that everything is 
driven off of the username in the mapping with no group but the mapping file 
supports regular expressions to do some mapping.

As detailed in:

Would it be possible to include either the primary group or a list of groups in 
the username string for mapping in the pg_ident.conf file?

For example:
User Tom is a member of the "sales" primary group in the DEV domain with a 
secondary group of "users". When he attempts to login, postgres builds the 
following username for matching purposes: "Tom:sa...@dev" or 
"Tom:sales,us...@dev". At that point we could map the user to a specific 
postgres based on the group(s) instead of using username prefixes or hard 
coding each name.
