User:Arms & Hearts reports that they're getting a username/password error message when attempting to access content they're authorized for:

When I click on "access collection" for any collection that I have access to (or should have access to—I'm not sure if there's a difference) I'm taken to a page on oclc.org that tells me I've entered an incorrect username or password, and prompts me to try again to login.

They've attempted logging out and back in both in the Library Card platform and in EZProxy to no avail. They have an active Library Bundle authorization and therefore should be authorized to access the content they're attempting.

This appears to be a result of their username containing an ampersand. The account SamWaltonTest& reproduced this error.
