InvalidCredentialsException: Credentials cannot be used for NTLM authentication

PRPC Version - 7.1.5

We are using Microsoft share point as ECM system.

I'm configuring an ATOM server data instance, and getting below error when I do test connectivity.


Couldn't connect to Atom server located at <location name> <p> 401-Unauthorized

During this time PRPC log says below

2016-04-07 03:08:37,765 Credentials cannot be used for NTLM authentication: com.pega.apache.commons.httpclient.UsernamePasswordCredentials

I did looked at few posts on PDN which says https://pdn.pega.com/release-note/pega-connect-cmis-support-ntlm-authentication NTLM authication scheme has been activated after ML8.

Would be keen to hear about

  • Any other observation of this issue?
  • Whether there is any acknowledgement of a product issue in this space, official re-mediation to existing PRPC versions?

Thanks,
