LDAP
Datasentinel seamlessly integrates with LDAP for user authentication.
The Datasentinel frontend is stored as a Grafana plugin and utilizes the Grafana authentication method for streamlined user access and secure login.
To configure LDAP authentication, the Grafana configuration files must be modified accordingly. See Grafana documentation
Although LDAP authentication can be used with any version of Datasentinel, it is much more integrated starting from version 2023.03, which was released in March 2023.
The management of profiles, privileges, and role-based access continues to be handled through the Datasentinel interface, even when LDAP authentication is enabled.
Edit main config file
/datasentinel/soft/grafana/src/github.com/grafana/grafana/conf/defaults.ini
Enable ldap authentication in the auth.ldap section.
