User, which is Domain Admin and member of local Administrators group, was added into QMM Project, Delegate. When logging in as this user and attempting to open QMM console, the error is generated: LDAP error 0x31. Invalid Credentials (8009030C: LdapErr: DSID-0C0906B5, comment: AcceptSecurityContext error, data 52f, v4563)
However RUM console can be opened with no issues under the same account. Also ADSIedit can connect to ADLDS database and see the content of the QMM Project
