Principal user@MYDOM.EXAMPLE.COM not found

Resolving the problem

This error can occur if the GCD does not have a directory configuration for the MYDOM.EXAMPLE.COM Active Directory. In Administration Console for Content Platform Engine, select the name of the Content Cortex domain and then click Directory Configuration.

This error can also happen in a multi-domain environment if the GCD does not have the directory configuration for a client domain set up, as each client domain must individually have its directory configuration set up.
