ypchsh

Hi, I have a problem when trying to use the ypchsh command, the error that follows is this: ogin shell [/bin/bash]: /bin/csh Error while changing the login shell. The login shell has not been changed. In the /var/log/messages on the yp server is this : Jan 30 10:25:46 sagan kernel: fh_verify: //pazz permission failure, acc=1, error=13 Any help appreciated, thanks, Paul
