Hi,

nis supports 32-bit uids pretty well but I discovered mknetid does not -
it hard-codes a uid limit in the insert_user() function.
This has the effect of ignoring all users with uid above the 16-bit limit,
so the netid table that is created can be missing such users.

A suggested fix is attached. It's quite ugly and probably needs
reworking to make proper use of uid_t as well as some clever indexing
to avoid blowing out the uid_liste[] array to 4Gbytes.
But on a system with sufficient memory, it works.

I expect this to be present in 3.17-32 as well.

kind regards
Vince
