Hi Pete,

Only the `maxids' field is screwed up. There is a command called (I
believe) maxids to (re)set the current maximum user and group id's.
OTOH, the patch I sent to the list earlier actually fixes the `screwing
things up in the first place' part of the problem.

At least I am interested in hearing some comments. The pdb library
actually already was an overhaul of some previously existing
authentication mechanism. And the pdbtool is just a dumb interface to
modify things in the pdb databases. I added some functionality to the
pdbtool to make it easier to use by scripts.

btw. Some of the lacking areas might even be explicit design decisions,
such as the trusted-servers/untrusted-clients security model, which is
`inherited' from AFS/Kerberos.
