at $JOB there are clients where 32bits is starting to chafe.

Has anyone expanded them?


This is starting to become a serious limitation in some places.

Especially large institutions with Samba active.

Samba uses a map between SIDs (session IDs) and UIDS, but it's a 
sparse map and due to various issues the mapping is not able to re-use 
numbers well.
