You are wrong, unix_chkpwd does NIS (at least in the szenario I just
tested). After changing unix_chkpwd from 4755 root:root to 2755
root:shadow a NIS user can not unlock the terminal he has just locked
himself with vlock anymore.
The NIS-server is configured with
* : * : shadow.byname : port
* : * : passwd.adjunct.byname : port
and
MERGE_PASSWD=false
