when I log in as UrbachG instead of urbachg it allows me to login but any filter that I have created crashes with the following error

ERRORS:
Could not getRequest search with this id.

this is very confusing and is causing complaints.
I am guessing that this weakness in your login code / data model will cause many other knock-on related problems. Like the previous issue I found(JRA-2148) where users cannot see issues that they have raised - again quite confusing.

any fix here would be much appreciated.

cheers,
