Authentication error 409 - DIGEST-MD5

Hi,

I’m trying to authenticate spark + presence server (CISCO), but I’m facing some issues.

Basically, it seems my client authentication type is PLAIN, but the server can’t authenticate because it uses DIGEST-MD5.

The log shows an error which the code is 409 (What does it mean?).

How do I change the authentication type in Spark client in order to match with the server’s authentication and solve this problem?

Some pictures with the error log are attached.

Thanks in advance,

Gabriel.
