I see it just now. This attribute must be a valid shell on the client i.e /bin/bash or /bin/sh or what else you want but a valid shell, I don't think that /bin/test permit you to log in the client (on centos5.3 the program /bin/test doesn't exist !!) thus the first thing you can do is to change the attribute login shell from /bin/test to /bin/bash then try to login the station with user t01. For further verification of the server side you can do a request ldapsearch : ldapsearch -x -h 192.168.5.1 -b "dc=vfds,dc=local" 'uid=t01' and show the output
