About Owncloud

OwnCloud is an open-source file hosting application provide services for business and personal use. It is a flexible tool which manages file and data synchronization. It helps users to store files, folders, contacts, photo galleries, calendars and more on a server of your choice. It is a self-hosted file sync and share server that is all under your control. Content can be shared by defining granular read/write permissions between users and groups. To use application effectively you can be logged in into Owncloud using SSO. Single sign-on helps employees save time, prevents lost or forgotten passwords, and reduces the risk of password theft.

Challenge

To achieving Single Sign On between Identity Provider(Wordpress/Joomla/Drupal) and Service Provider (Owncloud) both need to supports SAML. Owncloud supports SAML connection but it is supported in the Owncloud enterprise version. Single Sign On user can login into IdP based site and gain access to Owncloud services. Identity Provider can manage identity details of users and give the authorization to use the resources of the service provider.

Solution

The SAML IDP plugin makes SAML connection between Wordpress and Owncloud. miniOrange SAML IDP Plugin is an authentication component that serves identity details to the service provider for on-premise, cloud and mobile. SAML single sign-on (SSO) compliance makes it possible for users to authenticate through identity provider when they log in to Owncloud applications. SAML SSO module acts as an Identity Provider which can be configured to build the trust between the module and Owncloud Service Provider. SAML exchanges security and identity related information such as authorization and authentication. User can easily login to Owncloud using their Wordpress credentials.

How miniOrange SAML plugin can work for Owncloud?

a. Sign-in page URL	SAML Login URL from the Service Provider Tab.
b. Sign-out page URL	SAML Logout URL from the Service Provider Tab.
c. Verification Certificate	Upload the certificate from the Service Provider Tab

• STEP 3 :If your Service Provider needs extra user attributes or custom attributes to be sent in the SAML response then you can configure this under the Attribute/Role Mapping Tab.
