Hello. I'm a recent mac convert and am connected to my university's ethernet. Periodically I receive the following error message: "An S/Ident request to MacLeland Agent returned an error of type 131. Try to log in again." When I receive this message, I'm not trying to log in to anything. In fact, the most recent message popped up while I was using word processing software, which makes the error message seem random and unprompted. Does anyone out know what could be causing this? Thanks.
