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

I did looked at few posts on PDN which says https://community.pega.com/knowledgebase/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,

Sadaan

Issue has been resolved. PEGA 7.1.5 does not support NTLM authentication for CMIS. We did not do any changes @ PEGA.

We have disabled NTLM authentication\windows authentication @ share point and turned on ONLY basic authentication.

As you discovered, CMIS connectivity to Microsoft Sharepoint using NTLMv1 is supported in Pega 7.1.8 and later.

I encourage you to upgrade to the latest version of Pega to get the best results when connecting to your ECM.
