Hi Krileon,
Thankyou. At this stage I am now using the CB login module and have set the 'Login Field Type' to Username, email or enabled CMS authentication plugins. This is working to the point that A new Active Directory user can login and their Joomla + CB account is created but they still require Admin Approval and Email Confirmation. They get the following message when they login:
Your registration process is not yet complete! Please check again your email for further instructions that have just been resent. If you don't find the email, check your spam-box. Make sure that your email account options are not set to immediately delete spam. If that was the case, just try logging in again to receive a new instructions email.
Is it at all possible to disable these features?
