UCS comes with a central login page. Logging in to the UCS web interface is done with the credentials of the respective domain account. On the portal, the login process can be started either via the user menu an then Login or by clicking on the entry in the portal itself. If a site (e.g., a UMC module) requires a login, it will redirect to the central login page. To sign out, the entry Logout in the user menu can be used.
By default a login does not use single sign-on. The login can be changed to use
single sign-on (SSO) via SAML (SAML identity provider). To configure this,
ucs-sso.[Domain name] must be reachable and the Univention Configuration Registry Variable
portal/auth-mode has to be set to
saml. For the change to take
effect the portal server needs to be restarted: systemctl restart
univention-portal-server.service. The login using the user menu has now be
changed. Portal tiles have to be adapted manually. The default portal has a SSO
login tile preconfigured which can be activated using the portal edit mode.
After successful login, a session is valid for all UCS systems of the domain as well as for third party Apps if these support web based SSO. It is possible to enforce a login on the local system by clicking on the link Login without Single Sign On.
In the login mask, enter the Username and Password of the corresponding domain account:
When logging in with the
Administratoraccount on a Primary Directory Node or Backup Directory Node, UMC modules for the administration and configuration of the local system as well as UMC modules for the administration of data in the LDAP directory are displayed. The initial password of this account has been specified in the setup wizard during the installation. It corresponds to the initial password of the local
Administratoris also the account which should be used for the initial login at a newly installed Primary Directory Nodesystem.
In some cases, it might be necessary to sign in with the system’s local
rootaccount (see Administrative access with the root account). This account enables access only to the UMC modules for the administration and configuration of the local system.
When logging on with another user account, the UMC modules approved for the user are shown. Additional information on allowing further modules can be found in Delegated administration for UMC modules.
The duration of a browser session is 8 hours for the SSO login. After these, the login process must be carried out again. For the login at the local UCS system, the browser session will be automatically closed after an inactivity of 8 hours.
By installing a third-party application, such as privacyIDEA, it is possible to extend the UCS web interface authentication with a two-factor authentication (2FA).
