Description Todd Cullum 2022-06-24 23:27:32 UTC

When using the caServerKeygen_DirUserCert profile with UserDirEnrollment auth type, usre are able to get a certificate for any UID I please simply by entering their name in the Subject information fields. This occurs only when Directory-based authentication is enabled, which is disabled by default.
