Which auth are you referring to? I have my IRI node's remote port password protected, and when I add --iri http://user:pass@nodeip:port I'm getting:

Error: Invalid Response:

I'm using https://github.com/goestin/iota-peer-manager though

I can confirm that when I remove the REMOTE_AUTH = user:pass from the ini file and restart the server, I am then able to use IPM. So it doesn't support password protected nodes.
