IssueError 401: You are not authorized to perform this operation
SSO fails

A Domino 6.5.2 system has been installed with the ClearTrust agent and SSO using mapped User Principal Names has been configured however after the initial ClearTrust authentication a subsequent HTTP pop-up authentication box still appears asking for Domino credentials.

The problem is caused by a known bug in the initial release Domino 6.5.2 system and was quickly fixed by IBM (for further information see the IBM Technote (FQA) ref 1177645 at http://www-1.ibm.com/support/docview.wss?uid=swg21177645 with the title "After upgrading to Domino 6.5.2, authentication via DSAPI filter returns wrong user name".


The RSA ClearTrust Domino agent has been fully qualified against 6.5.1 and it is known that this version does not exhibit the issue.  It is also possible to upgrade to later versions of 6.5.x however these later versions will not have been qualified for use with the ClearTrust Domino 4.6 agent and support can only be supplied on a "best endeavours" basis where changes between the later version and 6.5.1 cause an interworking issue.

The IBM technote advises installation of either 6.5.3 or Domino 6.5.2 Fix Pack 1 (FP1) however it also gives an alternative approach to resolve the issue without any additional software.  This alternative approach is to reconfigure settings in the Domino server by changing the "Internet Authentication" field on the Security tab of the Server document to "More name variations with lower security",. for more specific detail on what this implies contact IBM Customer Support.  Remember when considering setting this field that an enhanced level of security has now been applied to the Domino server by using the ClearTrust Domino agent.

Although the ClearTrust agent was originally qualified only on 6.5.1 Rooben Garakanian (then CE manager) accepted that versions such as 6.5.4 were valid versions to submit defects to engineering since engineering could only obtain copies of 6.5.4 to qualify patches on anyway and that copies of 6.5.1 were not currently available.

This does not change the fact that QA of the product has only been carried out on 6.5.1 and that subsequent versions could easily introduce unknown factors as seen by the 6.5.2 version.
