A regular expression specifying one or more groups. Use a backslash before characters in the group name that have a special meaning in regular expressions.
To specify a Windows Active Directory domain, use either a single forward slash or two backward slashes between the domain name and the group name. The following formats are equivalent:
Note: You must include the domain name for all domain groups. If you omit domain information, the server looks for groups defined on the local computer.
To specify a local group, use no domain name, or specify the local computer name for the domain name.
To specify a Web Edition group, use Reflection for groups in the built-in User Manager directory, or use the domain name of any added LDAP server. To ensure that your group settings work as expected, confirm that the LDAP server domain name you specify here matches the name you specified in User Manager. (Connect to User Manager, click LDAP Server, select your server, click Edit and confirm the value entered for Domain Name.)
