To view or edit encyclopedias through the System Architect XT, you need the same permissions as you do for using the System Architect. In other words, an individual must exist as a user in the catalog, and log on by using the DomainName\UserName and password to view encyclopedias. If you are already logged in to the domain when you start System Architect XT, you are not required to enter your login credentials.
Another requirement to access an encyclopedia through the System Architect XT is that its property configuration files are up-to-date. To update the configuration files, open an encyclopedia with a System Architect version that is the same version as System Architect XT, compile the property file and make it up-to-date.
Without this update, the encyclopedia is considered out-of-date, and you cannot open the encyclopedia. Therefore, you must consider opening encyclopedias with a standard copy of System Architect as a part of any installation, upgrade, or service pack that you apply.
Server roles and permissions
The System Architect XT Domain Account (also referred to as the impersonation account) needs to have read and write permissions on the TelelogicEnterpriseCatalog database. For SQL Server implementations, these are the db_datareader and db_datawriter permissions.
Note Even if a user logs in as a Reader, the XT domain account still requires read and write access to the catalog database.
