For certain setups we don't need the ADMIN_USER_ID to be set. It is mainly needed for bootstrapping the internal idm and the initial role assignment. If roles are assigned by other means (e.g. OIDC claims in the future) we don't need it. This makes the ADMIN_USER_ID optional, also if ADMIN_USER_ID is unset we don't need to configure a password for the admin user. We will still generated the admin_id and password when running 'ocis init', but it is ok to run manual setups without those settings.
Idm
The IDM service provides a minimal LDAP Service, based on Libregraph idm, for oCIS. It is started as part of the default configuration and serves as a central place for storing user and group information.
It is mainly targeted at small oCIS installations. For larger setups it is recommended to replace IDM with a “real” LDAP server or to switch to an external identity management solution.
IDM listens on port 9325 by default. In the default configuration it only accepts TLS-protected connections (LDAPS). The BaseDN of the LDAP tree is o=libregraph-idm. IDM gives LDAP write permissions to a single user (DN: uid=libregraph,ou=sysusers,o=libregraph-idm). Any other authenticated user has read-only access. IDM stores its data in a boltdb file idm/ocis.boltdb inside the oCIS base data directory.
Note: IDM is limited in its functionality. It only supports a subset of the LDAP operations (namely BIND, SEARCH, ADD, MODIFY, DELETE). Also, IDM currently does not do any schema verification (like. structural vs. auxiliary object classes, require and option attributes, syntax checks, …). Therefore it is not meant as a general purpose LDAP server.
