The Configuration Manager CMEnroll tool fails on a Mac client computer with the following error:
Error recieved: Server Connection failed. HTTP Response code is 400 and reason is Bad request.
This issue can occur if the user has the special characters "&" and "<" in their domain password. CMEnroll.exe does not encode the "&" and "<" special characters correctly for Mac based clients.
To work around this issue, have the user change their password so that it does not contain these special characters.
