Description of problem:
ypbind will check to see if the current NIS server is the fastest every 1 minite.
But, manpage of ypbind says it's 15 minites.

This occurred with a fix of https://bugzilla.redhat.com/show_bug.cgi?id=198689.
The fix includes this part:

@@ -1024,7 +1049,8 @@ test_bindings (void *param __attribute__
 	pthread_exit (&success);
 
       lastcheck += ping_interval;
-      if (lastcheck >= 900) /* 900 = 15min. */
+      //if (lastcheck >= 900) /* 900 = 15min. */
+      if (lastcheck >= 60) /* 900 = 15min. */
 	lastcheck = 0;
 
       lastcheck = test_bindings_once(lastcheck);

So, it was changed into 60 second (1min) clearly here. But, I cannot see why this change is needed for the fix of BZ198689. 

The fix on BZ198689 was introduced from rhel4.5. So, this can be a regression from rhel4.4 or before.

Version-Release number of selected component (if applicable):
ypbind-1.17.2-13 and later

How reproducible:
Always

Steps to Reproduce:
1. run ypbind 
2. check the interval of "Pinging all active server" message
  
Actual results:
ypbind checks it every 1 min

Expected results:
ypbind checks it every 15 min

Additional info:

RHEL5 has this same change, which means the same bug.
RHEL6 doesn't have this change.
