One issue to be aware of is that the default config will not include
UIDs and GIDs that are less than 500 in their respective NIS maps.
This behaviour can be changed by editing the /var/yp/Makefile.

Subject: [SL] NIS weird behavior


Dear all,

I have a cluster on which I set up NIS and NFS. For the first three user 
accounts I set up, there is no problem using them. But later I added a 
few new users, and they could not login to any of the NIS client. They 
complained that there are not these users. However, if I use ypcat, 
yptest, ypwhich, etc., on each client thest tests all pass. If I list 
the contents of the NFSed /home directory, I found that the system could 
not recognize the uid and gid of these new accounts. That is, it seems 
that NIS setup is fine, but somehow the system does not use those 
informations. I am totally exausted by this problem now. Can someone 
give me some clues? Thanks in advance!
