epadmin-realm
epadmin realm target — Backs up, restores, and administers local authentication realms.
DESCRIPTION
A security realm is a set of configured security providers, users, groups, security roles, and security policies that provide authentication of users and machines and manage authorization or rights to use resources. Nodes can be configured to use one or more security realms or use the simple default realm. The Spotfire Streaming security model is documented in StreamBase Security Model.
Use the epadmin realm target to view the current set of realms active for the specified nodes, to back up and restore a realm's settings, and to get and set realms for activation.
The realm target has five commands:
The designation [ in syntax examples is a reminder that this
command requires either the global parameter sn|ad]‑‑servicename or the ‑‑adminport and
‑‑hostname combination to identify the node or cluster
of interest.
epadmin backup realm
Backs up a local authentication realm to a file.
epadmin[backup realm --file=defaultRealm.backup epadminsn|ad][backup realm --name=myLocalAuthRealm --file=localAuth.backupsn|ad]

epadmin[display realm epadminsn|ad][display realm --name=myLocalAuthRealmsn|ad]

epadmin getadmin realm
Returns the authentication realm currently being used for node administration. This is useful when more than one realm is configured for a node.
epadmin [sn|ad] getadmin realm
epadmin restore realm
Restores a local authentication realm settings from a backup file made with backup realm. This command replaces the entire configuration of the specified realm with the contents of the backup.
epadmin[restore realm --file=/opt/backups/realm.backup epadminsn|ad][restore realm --file=/opt/backups/realm.backup --name=myLocalAuthRealmsn|ad]

epadmin setadmin realm
For a node with more than one local authentication realm activated, sets which realm is to be the primary administration realm going forward.
The user specified with the --newrealmusername
parameter must have administrator privileges (described in Role to Privilege Authorization)
in the new authentication realm being set for node administration, otherwise the
command fails. This ensures that there is at least one user in the new realm that
has node administration privileges.
If the new realm has the current OS user name defined as administrator (just as the
default realm does), then you only need to specify --newrealmpassword. The make this practical, especially if your
alternate configuration requires passwords, first change the password for the
default user in the active default realm with epadmin change password. Then specify
the same password in your alternate realm's configuration file. See Replacing the Default Realm.
epadmin[setadmin realm epadminsn|ad][setadmin realm --newrealmusername=administrator --newrealmpassword=supersecret epadminsn|ad][setadmin realm --newrealmusername=administrator // password prompt displayed epadminsn|ad][setadmin realm --name=myLocalAuthRealmsn|ad]

|
