Symptom: "Error 7821 User cannot be added", appears during the installation of the SES-managed SecureDoc client software.
Cause: This error means that no more users or computers can be added to the database.
One possible reason for this could be that the Administrative Account in SQL does not have the necessary privileges to write to the database across a network. Traditionally the solution has been to provide the SQL Administrator Account with the following DB Roles:
DB_Owner
Public
SD_Admin
SD_User
Resolution:
1. Verify the SQL admin account has these DB roles set and set them if any of the above roles are missing.
2. Another possibility is that the SDConnex setting for Remote Installation Settings is set to zero and does not permit any new users to be added.This scenario may need to be checked and resolved on EACH SDConnex server in use, as SDConnex stores its settings locally on each SDConnex server.
To resolve this:
Open SDConnex and view the Remote Installation Settings.
Verify that the installation counters for users and computers aren’t set to 0 (zero). If this is the case, increase these values.
3. In one case, the client could not be added to the DB, even though these roles had been enabled for the administrative account. In this case, it turns out that the administrator installed SQL Express without ACTIVE DIRECTORY DOMAIN PERMISSIONS.
To resolve this, provide the Administrative Account AD Domain Permissions.
NOTE: As a rule of thumb, unless SDConnex servers are being used for different purposes (i.e. connecting to different SES databases), one should always ensure that all SDConnex Servers in an environment are set identically - if changing settings on one, make sure the same changes are applied to the others.
