Description of problem:

[root@tin ~]# ypcat -k hosts | grep "tin "
tin 160.129.138.133     tin     tin.structbio.vanderbilt.edu
[root@tin ~]# /etc/init.d/nscd start
Starting nscd:                                             [  OK  ]
[root@tin ~]# ping tin
ping: unknown host tin
[root@tin ~]# /etc/init.d/nscd stop
Stopping nscd:                                             [  OK  ]
[root@tin ~]# ping tin
PING tin (160.129.138.133) 56(84) bytes of data.
64 bytes from tin (160.129.138.133): icmp_seq=0 ttl=64 time=0.018 ms
[root@tin ~]# grep hosts /etc/nsswitch.conf 
#hosts:     db files ldap nis dns
hosts:      files nis dns


Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1. use nis and set hostname in nis hosts file to something like (3 letters):

160.129.138.133     tin     tin.structbio.vanderbilt.edu
2. set nsswitch.conf as above, try to ping tin, try traceroute, try "hostname -s"
3. turn off nscd then try all of above
  
Actual results:
when nscd is on I always get unknown hostname. when nscd is off the command succeeds

Expected results:
The command should succeed whether or not nscd is on or off.
