-Setting up a client (SAML "Service Provider" - short SP) to use Admidio's user accounts for logging in consists of two steps. If both the IdP (Admidio in our case) and the SP (Odoo in this document) support metadata loading, the setup is very straightforward and easy. Otherwise, one has to copy URLs manually to the client, but Admidio already provides these in a single place, so this situation is not as bad, either.+Setting up a client (SAML "Service Provider" = "SP") to use Admidio's user accounts for log-in consists of two steps.

   * Odoo does NOT automatically create a new user account if a successful login from an unknown Admidio account occurs. Instead, one first has to create a new user (or connect an existing user) and connect that user with the proper Admidio user account name. In Admidio's SAML client config, you can select whether to use the numeric user ID, the login name or the email as "User ID field". Whatever you choose determines which value must be entered in Odoo's user connection field.   * Odoo does NOT automatically create a new user account if a successful login from an unknown Admidio account occurs.

Whatever you choose determines which value must be entered in Odoo's user connection field.
 +  * Odoo does not support SAML Single-Log-Out, so logging out from Odoo will not log the user out from Admidio or other SAML or OIDC clients.
 +  * Odoo's SAML User IDs are case-sensitive. If your Admidio username is "Member", you can log into Admidio using "member", but in Odoo's SAML user ID you must use the original "Member".

   * If odoo is behind a reverse proxy (e.g. Nginx Proxy Manager), correct proxy settings both in Odoo and the proxy itself is vital to make sure that the SAML endpoints in the metadata file and the actually called endpoints actually use https.

     * Make sure the reverse proxy sends all proper proxy headers, including X-FORWARDED-HOST, which is used by odoo to detect a reverse proxy setup. Nginx Proxy Manager by default does not send this header. It is also not easily possible to add this header in the "Advanced" tab of the Proxy Host in NPM. Instead, one has to add Custom Location for "/" and set the X-Forwarded-Host header there via <code>proxy_set_header X-Forwarded-Host $host;</code> You need to duplicate the forwarding host information from the main host:{{ :en:2.0:sso:sso_saml_odoo_12_npm_x-forwarded-host.png?direct&400 |}}     * Make sure the reverse proxy sends all proper proxy headers, including X-FORWARDED-HOST, which is used by odoo to detect a reverse proxy setup.
