and stumbled upon the behavior of Authentication.UserGroups when using LDAP authentication.
The product guide says: "List of user groups that the authentication process is applied to".
Is my observation correct that for LDAP authentication the value of Authentication.UserGroups depends on the table "User attributes to retrieve"? So it is not exactly "list of groups the authenticated user is member of" but more like "list of values configured in 'User attributes to retrieve'"?
My second observation is that requesting more than one attribute interferes with Authentication.UserGroups in combination with the operator "contains".
