--runasdn (-u)

--runasdn is used to authenticate the user to the LDAP server. The argument is a value equal to that of the Distinguished Name (DN) of the user authorized to run amadmin; for example

--runasdn uid=amAdmin,ou=People,o=example.com,o=isp .

The DN can also be formatted by inserting spaces between the domain components and double quoting the entire DN such as: --runasdn "uid=amAdmin, ou=People, o=iplanet.com, o=isp".
