From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-0.1.25smp i686) I've setup my system so that it gets its password information from my nis server. The commands domainname and ypwhich show that I'm properly setup to pull "nis maps"(?) from my nis server. If I do a ypcat yppasswd I get the password file from my nis server, yet when I try to log into the system, I get an error that the username is not found. Reproducible: Always Steps to Reproduce: 1.Setup NIS, make your nis server an sgi machine running Irix 6.5. I'm not sure if this is required or not to reporduce the bug 2.login as a user how is defined in the password file on the nis server machine. 3.You cannot log in. 4.as root do a 'su - username'. See error "su: user username does not exist" Here is an example... [root@phyppro1 /root]# su - adler su: user adler does not exist [root@phyppro1 /root]# domainname phy [root@phyppro1 /root]# ypwhich physgi00.phy.bnl.gov [root@phyppro1 /root]# ypcat passwd | grep adler adler:XXXXXXXX:29472:29472:Stephen S. Adler,BNL,Physics 510; 2-67, (516) 282-5682,:/users/usr0/adler:/bin/tcsh Note: I replaced the password field with XXXXXXX since I didn't not want to proadcast this hash across the nextwork.
Do you have a firewall enabled? As noted in the release notes, this will block any RPC-based services such as NIS. Is "nis" listed on the "passwd:" line in /etc/nsswitch.conf (it should be, but there's no harm in checking)? Do you get any output from "getent passwd adler"?
Everything should work fine if you either use /usr/sbin/authconfig to configure the yp server or if you edit /etc/nsswitch.conf and enable nis lookups. Does this help to get it running?
I believe I've found the problem. the file /etc/nisswitch did not have 'nis' entries for the password file. I don't understand why ypcat worked, even though /etc/nisswitch did not have and 'nis' entry in the file for passwd and group files. It would be nice that by default, nis was the last in the list of "nis options". In anycase, once I added "nis" to the list of "where to get file from", the system was able to identify the user at login.
