Thanks LucD,

The requirement for one of the environments is to add domain\username as per the attachment and I have done this manually via right click manage ---> permissions... Add user and select the role. So like to amend the script to do this.

If i try to add a domain\username via security & users --> users --> add user I get the error 'Invalid characters found in user name. Please use only alpha-numeric characters. As discussed previously.

I hope that helps.

Please advise thanks

Many Thanks
