Description of problem:
After updating Enterprise AS 3 kernel to 2.4.21-27.0.4.El.smp, NIS and CVS no longer function

Version-Release number of selected component (if applicable):
ypbind-1.12-5.21.1; kernel-2.4.21-27.0.4.EL.smp

How reproducible:
Couldn't Reproduce

Steps to Reproduce:
1.service ypbind restart
2.
3.
  

Actual Results:  Shutting down NIS services:                                [  OK  ]
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.

Expected Results:  Shutting down NIS services:                                [  OK  ]
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.
Found server <NIS server name>

Additional info:

Trying to login to an NIS account from the client shows the following in the
server's /var/log/messages (server is "skippy", NIS domainname is "dippy"):

---------------------
Apr 27 09:56:17 skippy ypserv[2348]: refused connect from 192.168.168.61:955 to
procedure ypproc_match (dippy,passwd.byname;0)
Apr 27 09:56:21 skippy ypserv[2348]: refused connect from 127.0.0.1:808 to
procedure ypproc_domain (dippy,;0)
---------------------

'ypcat passwd' from the client gives the following:

---------------------
No such map passwd.byname. Reason: No such map in server's domain
---------------------

I think that the client isn't actually binding to the NIS domain server.
I am not certain whether a message reporting a successful bind is supposed to be output.

When I try to login to CVS I get the following:
----------
cvs [login aborted]: connect to skippy(127.0.0.1):2401 failed: Connection refused
----------

This bug is similar to 155967, but I believe different enough to warrant it's own report.
