We have a NIS master M and a slave server S in a domain D. Sometimes,
after issuing the command "cd /var/yp/D; make all" on the master, the
slave (which is also a client) can't find some of its users:

- "lsuser U" reports "User U does not exists", but
- "ypmatch U passwd" prints out the correct record.

This happens when S is its own server. After switching to the master
server by "ypset M", lsuser works, but is dead slow (and appears to
get slower every time).

Has anybody seen this before? Any ideas what the reason might be?

Thanks in advance,
Bernd
