[Zope] SecurityGetUser object as text

I have the following Extention def cryptPass(self,username,password): import crypt return crypt.crypt(password,username[:2]) When I call this with, cryptPass(_.SecurityGetUser(),'some pass phrase') Zope returns an error because it cannot perform a slice on the object that SecurityGetUser() returns. Is there a way to just get the text value of that object? -- Bryan C. Andregg Duke University Medical Center Programmer Dept. of Anesthesiology e <bryan.andregg@duke.edu> p +1 919 684 6201
