+	<description><![CDATA[Using the SSO & SAML app of your Nextcloud you can make it easily possible to integrate your existing Single-Sign-On solution with Nextcloud. In addition, you can use the Nextcloud LDAP user provider to keep the convenience for users. (e.g. when sharing)
+The following providers are supported and tested at the moment:
+
+* **SAML 2.0**
+	* OneLogin
+	* Shibboleth
+	* Active Directory Federation Services (ADFS)
+
+* **Authentication via Environment Variable**
+	* Kerberos (mod_auth_kerb)
+	* Any other provider that authenticates using the environment variable
+
+While theoretically any other authentication provider implementing either one of those standards is compatible, we like to note that they are not part of any internal test matrix.]]></description>
