If you have a NIS client on HPUX and you’ve spent a few hours already trying to understand why on the earth “id” command keeps telling something like this:
bash-3.2# id sergeyt Can't find user sergeyt
And you’ve already checked all the pieces where NIS could brake, i.e. nsswitch.conf, ypwhich -m, ypmatch user_name passwd, nsquery, then try to ‘/sbin/init.d/pwgr stop’ and see if that would make a difference. Linux has a similar service called nscd (name server cache daemon) that has caused me a lot of trouble similar to the one mentioned above because both nscd and pwgrd cache not only positive but a negative responses as well.
Edit /etc/rc.config.d/pwgr file on HPUX server if you prefer this service to be disabled even if the server is rebooted.
