Description of problem: We need to document SSO feature support i.e (Single sign on) ENABLING steps from Dashboard cli commands.




Version-Release number of selected component (if applicable):
Ceph 4.1


How reproducible: Refer the upstream docs for enablement

https://docs.ceph.com/docs/master/mgr/dashboard/?highlight=sso#enabling-single-sign-on-sso


Steps to Reproduce:


1. Deploy 4.0 ceph-cluster on rhel 7.7/rhel 8.1 using ceph-ansible.
2.Launch the dashboard installed.
3. enable SSO from dashboard cli commands
4. Refer upstream doc for commands

https://docs.ceph.com/docs/master/mgr/dashboard/?highlight=sso#enabling-single-sign-on-sso

All the below steps needs to be added in the dashboard guide:

To configure SSO on Ceph Dashboard, you should use the following command:

$ ceph dashboard sso setup saml2 <ceph_dashboard_base_url> <idp_metadata> {<idp_username_attribute>} {<idp_entity_id>} {<sp_x_509_cert>} {<sp_private_key>}
Parameters:

<ceph_dashboard_base_url>: Base URL where Ceph Dashboard is accessible (e.g., https://cephdashboard.local)

<idp_metadata>: URL to remote (http://, https://) or local (file://) path or content of the IdP metadata XML (e.g., https://myidp/metadata, file:///home/myuser/metadata.xml).

<idp_username_attribute> (optional): Attribute that should be used to get the username from the authentication response. Defaults to uid.

<idp_entity_id> (optional): Use this when more than one entity id exists on the IdP metadata.

<sp_x_509_cert> / <sp_private_key> (optional): File path of the certificate that should be used by Ceph Dashboard (Service Provider) for signing and encryption.

Note The issuer value of SAML requests will follow this pattern: <ceph_dashboard_base_url>/auth/saml2/metadata
To display the current SAML 2.0 configuration, use the following command:

$ ceph dashboard sso show saml2
Note For more information about onelogin_settings, please check the onelogin documentation.
To disable SSO:

$ ceph dashboard sso disable
To check if SSO is enabled:

$ ceph dashboard sso status
To enable SSO:

$ ceph dashboard sso enable saml2
