Configuring NMC LDAP Authentication Error “External Role is invalid”

November 28, 2011

While Configuring login through external authentication via LDAP, you get the following error when adding the sAMAccountname in the external role window:

Error: “External Role <username> is invalid”

This issue is cased by either mismatching in the supplied username with what is retrieved by NMC from the Active Directory Or  an all lowercase username is entered in the External Role window, but an all uppercase username was retrieved by NMC.

Simply, to solve this issue, you have to enter an all uppercase sAMAccountname in the External Role window. As an example if the Account name is called ADMin , you cannot add it as admin or Admin , you have to add it like ADMin as it exists in the Active directory ( Case Sensitive)
