Ektron CMS400.Net Reference
Usually Membership users are not included in AD or LDAP directories. The default settings for Ektron CMS400.NET ignore AD or LDAP for Membership authentication.
If you want Membership users to authenticate with AD or LDAP, do the following steps.
web.config
file.LDAPmembershipUser
to true. It should look like this:<add key "ek_LDAPMembershipUser" value="true" />
When ek_LDAPmembershipUser
is false, Membership users are not authenticated with AD or LDAP.
