To integrate the SecSign ID Two-Factor Authentication with NextCloud you first need to setup an account with NextCloud and decide, where you want the server to be based off. More information on server options are available on the NextCloud website.

You also need access to the SecSign ID administrative panel. If you need assistance managing your administrative account please contact us.

In the NextCloud admin web site open the Apps dialog and select “Authentication & Authorization” from the list. Enable “SSO & SAML authentication”.

In the NextCloud admin web site open the SSO & SAML authentication dialog.
Select “Use build-in SAML authentication”.

Enter “uid” (without the quotes) as attribute to map the UID to. Then enter the Identifier of the IdP entity. It consists of the URL of the SecSign ID admin web site plus “/SAML_Login”.
For Example: https://admin.secsign.com/SAML_Login

Enter the same URL also as URL Target of the IdP where the SP will send the Authentication Request Message.
Then Select “Show optional Identity Provider settings …” Paste the PEM encoded certificate which you have configured to sign SAML responses in the SecSign ID Server as “Public X.509 certificate of the IdP”.
PEM encoding starts with “—–BEGIN CERTIFICATE—–“.
Click at “Download metadata XML”. Open the meta data XML file in a browser or a text editor.

Open the “SAML Service Provider” dialog in the SecSign admin web site and click at “Create new SAML response attribute”. Enter “uid” (without the quotes) as name in SAML response. Leave Format empty.
Select “SecSign ID Server” as Attribute Store and “SecSign ID” as Source attribute and save.

Select “New SAML service provider” and choose a name. For example: NextCloud. Select “SecSign ID Server” as NameID Attribute Store and select “SecSign ID” as NameID source attribute.
Leave NameID format empty.
Copy the URL from entityID from the metadata file to the “Service Provider Issuer” text field in the SecSign admin dialog.

Copy the URL from AssertionConsumerService in the metadata file to the “SAML response URL” text field in the SecSign admin dialog.

Leave RelayState, Audience Restriction and Auth Context empty.
Choose the user group to sign the SAML responses. For example: SAML response signers.
Select “Server selects” for Hash algorithm and “Server selects” for PSS padding. Select the SAML attribute “secsignid: from SecSign ID Server (uid)” and Save.

Keep the browser showing the NextCloud admin web site session open! Use another browser to test the NextCloud log-in. If it fails use the still open first browser to display the “Logging” dialog of NextCloud and see the error message.
