IIRC the failure is caused by an unsatisfied single valued gbean  
reference to the properties login module gbean from something in the  
admin console.  You need to find the gbean reference and change it to  
a collection valued reference so it's no longer a mandatory  
reference.  You can wrap a collection valued reference with  
SingleElementCollection to make it act like an optional single valued  

hope this is clear enough to help..
