I run Federation environment as IdP and the Affiliate Agent is unable to parse the SAML assertion as getting this error:
[ERROR] SAML_ParseException occurred while trying to parse the SAML Response received. Exception: Parsing SAML_Assertion: Could not parse date in <IssueInstant> Element(2011-08-11T13:12:47+02:00)
Indeed, the IssueInstant as the value 2011-08-11T13:12:47+02:00 which is not ending with Z as Zulu time. Is the 2011-08-11T13:12:47+02:00 UTC time ?
The format that the Affiliate Agent receive (2011-08-11T13:12:47+02:00) is not UTC. The time "2011-08-11T13:12:47+02:00" is local time and not UTC.
According to OASIS, the IssueInstant should be written in UTC format.
The time instant of issue in UTC, as described in Section 1.3.3
Our product works as designed and respects these guidelines. You should ask the SP side to send the IssueInstant in UTC format.
