phpCAS + validatePT error

[Derek Ethier]

Tomcat 5.5.20
CAS 3.0.5
phpCAS 0.5.1

With debug enabled for phpCAS I'm getting the following error on re-direct back
to the calling service once authenticated. I suspect that it is something
misconfigured in CAS itself, but I can't seem to figure it out.

	<cas:authenticationFailure code='INVALID_SERVICE'>
		ticket 'ST-2-7fo7TJ3cLAvPRYcxdaE0NiXpANG0ZvECCLh-20' does not match supplied
service
	</cas:authenticationFailure>

Is this particular issue solved in CAS 3.0.6 (and soon to be 3.0.7)? Or, is
this related to something else? Any assistance would be appreciated.
