Subject: Force new NetIDs to be unique.
X-Git-Url: https://git.zarvox.org/shortlog/month?a=commitdiff_plain;h=7debca91ec86d2faf1eb2e46b1bde50d9b105def;p=wp3.git

Force new NetIDs to be unique.

We reject new users that have netids already in the database.  When
merging two databases, the current database is considered the master
copy and a record from the merging database is discarded if there is
a netid conflict.
