FreeBSD 5.x with > 70k users?

[Ben Hockenhull]

Hi there,

I'm attempting to migrate an old BSDI system to FreeBSD.  The system in
question has about 71k users, with UIDs from about 2000 up to about 70000.
When I import the master.passwd file (formats are the same) to the new
system and try to rebuild the .db files, it fails with a pwd_mkdb: put:
Unknown error: 0 .

As best I can tell, if I import a small subset of the users (about 5k),
things work fine.  From what I understand, FreeBSD can have massive UIDs,
with the caveat that some applications may not like UIDs > 65535.

I did some research and found someone reporting an identical problem, but
didn't see that he'd found a solution.  Any input, pointers, solutions
greatly appreciated.

Ben
