Summary

ManageEngine ADSelfService Plus below build 6116 stores the password policy file for each domain under the html/ web root with a predictable filename based on the domain name. When ADSSP is configured with multiple Windows domains, a user from one domain can obtain the password policy for another domain by authenticating to the service and then sending a request specifying the password policy file of the other domain.
