Resolution

The NMAS error 1680 means the login sequence being called is not authorized.

Log into iManager
In the roles and task section click on NMAS
Click on NMAS Login Sequences
Verify that IPCExternal is authorized, if not check the box beside the login sequence and click Authorize

Next modify the domain mapped container.
Click on the NMAS tab
Click on the Login Sequences sub tab
Verify that IPCExternal is authorized, if not check the box beside the login sequence and click Authorize

Do the same for the Domain Controllers container and OESSystemObjects container.

Other sequences that should be authorized are GSSAPI, Kerberos, and NDS

Cause

The IPCExternal login sequence was not authorized
