So, I got this error…
Unknown WebCT username or invalid password. Please verify the admin user and password in the IMS Settings.
I assumed the username and password were probably right. I had to find my error somewhere else.
The error turned out to be one missing character out of the 57 character long glcid. Totally my fault.
I wonder how long I would have spent dorking around with the password trying to get it work and thinking I must be typing something wrong.
