FIM MA Export - Attribute Representation Failure and Odd Export Behavior

I've been noticing some bizarre FIM MA export behavior which started with the FIM Service throwing the failed-creation-via-web-services with the stack trace of:

Fault Reason: The request message contains errors that prevent processing the request.\r\n\r\nFault Details: &lt;RepresentationFailures xmlns="http://schemas.microsoft.com/2006/11/ResourceManagement" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;&lt;AttributeRepresentationFailure&gt;&lt;AttributeType&gt;EmployeeType&lt;/AttributeType&gt;&lt;AttributeValue&gt;Employee&lt;/AttributeValue&gt;&lt;FailureMessage&gt;Exception: ValueViolatesRegularExpression Target(s): <Removed Account Name>

Troubleshooting steps:

1.) I've checked the validation string, which is ^(Contractor|Employee)?$, on both the EmployeeType binding and the attribute, both of which match, and I still receive the above error message.

The source of the value is an HR MA constant attribute flow of "Employee" so it can't be any case or leading\trailing white space issue.

2.) Restarted the FIM Service and IIS Admin service on all FIM Service servers

3.) Cleared the FIM MA Connector Space

4.) Cleared the HR MA Connector Space

5.) Ran a Full Import and Full Sync on both the FIM MA and HR MA

Now here's where it gets weird.......some of the accounts get created and some fail. Also, if I rerun the export the failed accounts are created. In addition during the confirming import instead of seeing the newly exported person object count of say 5 updates, or whatever is the exported person count, I see 5 Adds and 50 updates. The additional updates seem to be caused by the workflows updating person object data on the FIM Service side but I've never seen that kind of behavior before.

With that said has anyone seen that kind of behavior and if so how did you resolve the problem?

Any help would be greatly appreciated!

Thanks,

Austin
