This patch fixes a bug in the ldap search which will only use the first 
mount point found in an LDAP entry.

For example if an ldap entry looks like this:

dn: cn=%T%I_apps, nisMapName=auto_home, ou=foo.bar
nismapname: auto_home
objectClass: top
objectClass: nisobject
nismapentry: foo.bar.ti.com:/vol/vol6/TI_apps
cn: %T%I_apps
cn: TI_apps

Then the auto_home map will only be used in /%T%I_apps

If you try to cd into TI_apps you'll just get an error.  The patch 
forces ldap_search to iterate through all of the different cn's in an 
entry so you can cd into either %T%I_apps or TI_apps and the proper 
directory will still be automounted.

Thanks,
Chris
