id: cannot find name for user ID

[Kusuma Sashidhar]

Hi,

When i try to login to a linux m/c (NIS client), it gives the error id: cannot find name for user ID xxx.

My NIS server is hp-ux. It works fine from other HP-UX NIS clients but not from linux NIS Clients.

Please help. I have checked permissions on home directory.

Regards,
Kusuma

hai,

Are you configured the /etc/nsswitch.conf file in linux with nis for hosts,passwd,networks as like other hp-ux clients.

Make the linux /etc/nsswitch.conf file as like hp-ux nsswitch.conf file. ID will work.

Hi Muthukumar,

I forgot to say that it doesn't happen for all the users on linux. which means that nsswitch.conf must be ok.

The only thing that I can think of is to check to make sure that the /etc/passwd and
/etc/group files are world readable.

check the NIS configuration with yptest. Can you able to change the user's passwd with yppasswd command.

Is ypdomainname command showing the NIS domain name.

what is saying grep user /etc/passwd; which user failed on ID. what is ur /etc/nsswitch.conf file entries. IF you are having files on passwd, the id will work for that user.

I hope your linux machine not having user as like in hp-ux server.

There still may a problem with your nsswitch.conf file even though it works for some users. Check to see if these users have local accounts on the LINUX box. Your nsswitch.conf may be configured to resolve passwords from local files only.

Double check to make sure the linux box is in the correct NIS domain.

Is the user allowed to login on linux machine??

From linux machine, can you do ypcat -k passwd|grep "user"

Also is there a command like nsquery on linux?? Can you check that the user is indeed resolvable from linux box??

Thank you all.

It is working now. I had done some stupid mistake regarding nis user and home directory.
