"Nglookup"

Hi ,

can Please somebody tell me "what is the purpose of this command
# Nglookup <user id>

There is no entry in google for nglookup

but i found it being used in ldap servers. may be to check the user info

but iam puzzled to find that why this doesnot exist in Google.

Thanks.

Maybe it is a self-made tool?
On such a machine, try

which nglookup
#or
man nglookup

Could also try a find to find that script/binary.
