You can configure My webMethods Server to obtain information about users and groups from external directory services. After configuring an external directory service, you need to take further action to identify the externally-defined users that you want to be able to access My webMethods. These users must be identified in the My webMethods Users role. For information about using external directory services with My webMethods Server, see Configuring an External LDAP, ADSI, or ADAM Directory Service and Allowing Externally Defined Users to Perform Actions from My webMethods.
