IMAP Login Splunk fails

Hello all,

I could successfully configure splunk imap plugin to retrieve mails from apple, but somehow it can't login to the REST API, I could reproduce the error by running the command line python script getimap.py:

DEBUG:root:about to dump mailbox support-wfp
DEBUG:root:decrypted splunk password
DEBUG:splunk.rest:simpleRequest > POST https://localhost:8089/services/auth/login [[REDACTED]] sessionSource=SDK
DEBUG:root:1userid/password combination for splunk user is invalid...
Traceback (most recent call last):
  File "getimap.py", line 405, in getMailbox
    latestTime = self.getCacheIDForMailbox(box)
  File "getimap.py", line 259, in getCacheIDForMailbox
    raise LoginError("1userid/password combination for splunk user is invalid...")
LoginError: 1userid/password combination for splunk user is invalid...
None
ERROR:root:ERROR - trying to select mailgox
rainbat:bin rainbat$

Somehow even hardcoded it doesn't accept the spunk.rest.simpleRequest, I am running OSX Lion on my MacMini, can anybody help ?

Best regards from Switzerland, Dominique
