RE: [EXTERNAL] Re: SAML Authentication Extension Group Membership
Ok thanks. I wanted to make sure to avoid troubleshooting something that was expected behavior.
I have debug logging enabled and am able to see the group names coming from my identity provider. The line says “Group” so I set saml-group-attribute: Group in guacamole.properties (documentation says Groups is default) But when I log in, the group membership is not recognized and connections and permissions are not being applied.
Is there any other way to troubleshoot why the group membership is not being recognized?
Thanks

The SAML extension does not currently implement Group membership.
Doesn't it? The "saml-group-attribute" property defines the SAML attribute used to retrieve groups.
Ah, yes, you're correct - I think I'm so used to answering that way for the other SSO modules that it was an automatic response...

Hi Simon,
The behavior you described is pretty much what I have experienced. Regarding the logouts, that is not working for me either. Perhaps these are ADFS specific issues as opposed to SAML in general.

Hey there,
I am also trying to find a solution for this topic.
Thanks to you, Ariel, I have successfully achieved logging in by transforming the claim in my IdP (ADFS) to Name Id - Format "Email-Address".
Now I am struggling with the fact that for every user logging in, I would have to add them manually to a group and also add every connection to every group manually.
That's where saml-group-attribute could come in handy...So I configured "Send group membership as claim" as an additional claim issuance rule and the debug messages look promising so far:
In my guacamole.properties, I explicitly set "saml-group-attribute: Group"
Of course I created this particular group beforehand in my guacamole-server currently backed by mysql.
It seems the attributes are not honored at all. It would be really great if I could fill a mininum of attributes like "Full Name","E-Mail","Organization", "Department".
Another question that arises: How can I still use the REST API with the saml-auth enabled? In Jira I read something about the idea to provide an extra button for the SSO authentication so that you can still login with local users. Is there any intel when and if this will be possible in the future?
PS: Logging out currently is not possible at all, am I right? But that is my least concern. ;)

Is there anything else that can be tried to troubleshoot that anyone can think of?
Thanks

I reviewed the settings in guacamole.properties and everything seems to be in order (I left the sections for LDAP in place). Debug logging shows the line: SAMLResponse has attributes: {http://schemas.xmlsoap.org/claims/Group=[CN=......OU=......DC=........]
In the extensions folder, I have the following in this order:
guacamole-auth-jdbc-mysql-1.2.0.jar
guacamole-auth-ldap-1.2.0.jar
guacamole-auth-saml-1.2.0.jar
I'm out of ideas of what or how to troubleshoot any further.
Thanks
