- I just spent a very frustrating few minutes on the phone with IBM's AIX
- support group in Austin (I think). My problem was/is that if you change
- the name (i.e. first field in the passwd file) of an existing user in the
- yp passwd map and update NIS, the AIX 3.2 NIS clients don't see the change.
- Thus you can change user xxxxxx to user yyyyyy and then rlogin to one of the
- AIX machines as yyyyyy and a ps -ef will reveal that the login shell is owned
- by user xxxxxx. Interestingly enough, "ypcat passwd" on one of the AIX
- NIS clients shows the correct username as will a "whoami."
-
- I called the support center to ask about this and was told I had a
- configuration error and that I would have to subscribe to AIX Serve and
- they would help me configure my machine. I tried to tell him that it looked
- more like a problem with NIS under 3.2 and he said they didn't know of any
- such problem ( I thought that was the purpose of reporting these things).
-
- Anyway, after about an hour or two of trying everything I could think of to
- determine the problem, I finally just did a "touch /etc/passwd" on one of the
- AIX NIS clients and, to my surprise, a "ps -ef" now gave the updated user
- name (yyyyyy in the example). So the good news is that I know how to solve
- the problem. The bad news is that such a solution seems to defeat the purpose
- of a distributed database. Having to "touch" the client /etc/passwd files
- is only slightly better than having to edit them all by hand!
-
- Has anyone else seen this problem? Is there any other way around it other
- than touching all the client /etc/passwd files?

- thanks,
