SASL DIGEST-MD5 Nonexistent realm

Trying to send IM’s from 3rd party unsupported software through OpenFire.

Getting the following errors:

javax.security.sasl.SaslException: DIGEST-MD5: digest response format violation. Nonexistent realm: xxxxxxxxxx.com (purposely obscurred)

I have found several posts, but no real info that has worked for me.

I have tried setting sasl.mechs to all of the mechanisms I know.

I have tried setting sasl.realms to what I believe my realm should be.

I have tried setting sasl.approvedRealms to what I believe my realm should be.

I have had no luck. I am looking for a point in the right direction please.

Thanks
