The problem with incorrect is the address used here is not the address in the location bar.\u00c2\u00a0 The one in the location bar has the values required to login. Instead I get something which causes users to be unable to login. Example: So we send someone to http:\/\/westga.view.usg.edu<\/a>. They get redirected to another address<\/a> in which we provide the glicid, insId, and insName. Correct breaks the frame and gives the browser back the same address. Incorrect breaks the frame and gives the browser back a different, non-functional address. Bad. Bad. Bad.<\/p>\n

WebCT Vista 3 used the Correct JavaScript which just passes back the address used. Blackbord Vista 8 for some reason changes what worked to Incorrect.<\/p>\n

Yay for first day of classes.

UPDATE 1:<\/strong><\/p>\n

It gets better… Bb Vista’s Custom Login and Institution List pages are unaffected (aka use the Vista 3 style JS). Only going to the generated logon page, loginDisplay.dowebct, has the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"
