Garret,
>>Do you have an alternative means of checking, like with perl,
python, etc?

Finally I cross-compiled Python and  got it workin on my target device. is
it possible to use python and parse /etc/passwd file for getpwnam() funtion.
I believe if it returns uid and gid of the given user is more than enough
correct?
>>Do you need to update your shadow password db setup?
 I dont have shadow password db setup in filesystem but ported openLDAP  to
my target device, is this help me ? The target device doen't have ethernet
controller support so i cann't communicate to host. Curently passwd and
group files in /etc directory as i mentioned above.

Please let me know your thoughts.

Regards
Vishwa
