ITA users can log in to the ITA desktop and web client (known as Tenant Portal for Colo users) to use the parts of the application they have been granted access to according to their user rights. They can manage their own user accounts but need to contact their administrator for other configuration needs or in case of any issues.
ITA administrators are administrators of the ITA application. ITA administrators can log in to the ITA web client and perform administration tasks related to the ITA application, such as user management, license management, and web branding for the look and feel of the web client.
This is not the same user as the server OS administrator described below.
ITA users and administrators can be local users (saved on the ITA server) or remote users authenticated by an AD or LDAP server, see more Configuring authentication servers used for managing remote users. Ensure there's at least one local ITA administrator account. This is needed for various reasons, for example in case there's a network related issue preventing connection to the authentication server or in case changes were made on the authentication server preventing ITA from getting the user data.
The server administrator is administrator on a deeper level, managing the server as well as the applications running on the server. This is the person doing server configuration and maintenance, such as configuring backup, secure connection, or file sharing.
This user may also be referred to as the Linux, OS (operating system) or Webmin user because:
- Linux CentOS is the operating system that comes with the ITA server installation and, as part of the ITA installation process, this first Linux server administrator must be created to subsequently be able to log in and perform server management tasks on the server after installation is complete.
- Webmin is the name of the web-based server management interface that the server OS administrators can use to perform server management tasks on the ITA server after installation is complete.
Webmin is not the only way to manage the server. You can also run commands directly on the ITA server by connecting through SSH without the need to open Webmin. SSH to the ITA server and log in with the server administrator credentials created during initial installation of ITA.
Since the ITA administrator and the server administrator are two different users, credentials are also separate and independent of each other. ITA administrator credentials are stored in the the ITA application database while server administrator credentials are stored by the server's operating system.
ITA administrator credentials are included in ITA backups. Restoring a ITA backup will reset ITA administrator credentials to whatever was stored in the backup. Server administrator credentials are separate and are not affected by restoring ITA backups.
