Thanks for response.
I check the servervariable.
actually, our users logon to server by user id like empployee number
we can get the logon_user it retrieve user id p00016175
we want to known about his name, first,last or full name.
which is store in domains server.
all logon users are register/member of domains server.
how can get/retreieve user name (first, last name or full name)
from the domains server ?
