Thanks for confirming!
I figured as much after seeing an absence of information in the WIKI and nothing in any of the configuration files that would enable or configure settings for the controls I mentioned.
…and I agree with you that this is typcially done in external authentication repository/services. I am in a temporary situation until we federate authentication between two different organizational domains…and the use of custom Alfresco authentication is the temporary means by which we will provide external users to access the repository. (I would have preferred to add them to our LDAP/Active directory or a secondary chained directory but have not been allowed to do so due to time frame and other business non-technical reasons.)
Thanks for responding to the question.
