Keycloak and SAML - Validation error

[LorisLombardo87]

Hi everybody,

after unsuccessfully tried to implement JWT for authorization we are now trying with SAML and Keycloak.

we have followed this article but when we try to validate it gives back the following error 

if i look at the SAML assertion i can see the attributes are there:

is there anything I can check to verify if the SAML request is in the correct format?

Thanks,
Loris

Can you compare your configuration in Keycloak and Qlik Cloud against the details in the following article?
https://community.qlik.com/t5/Official-Support-Articles/Qlik-Cloud-How-to-set-up-Keycloak-as-a-SAML-...

of course if you are using Keycloak you could use OIDC 

[LorisLombardo87]

Hi Marc, that is exactly how we have done the settings in Keycloak. 
we have tried OIDC as well, in that case it gives a First certificate issue, which i'm not sure what it is referring to.

please consider that our Keycloak in publicly available and it's certificate is a valid one.

thanks,
Loris

Here is a full SAML response that is working (also keycloak), can you check if there is any obvious difference with yours?

Hi Damien, thanks for you support!

I've loaded the two SAML assertions into https://samltool.io/ 

here is the one you shared

here is mine:

I cannot see any major difference

can you see anything strange?

please consider that our Keycloak is publicly available and the SSL certificate is a valid wildcard certificated emitted by a valid trusted authority

Thanks,
Loris

[Marc]

can you please confirm how you have configured the settings in Qlik Cloud

as your saml does not appear to have groups, but roles

[LorisLombardo87]

Hi Marc, 

it is configured like this.

BTW i'm not interested in groups or picture at the moment.

shall I leave that mapping blank?

also the error doesn't seem so refer to the group attribute but in general to the fact it cannot find the Attributes in the SAML assertion.

Thanks,
Loris

[Damien_Villaret]

Hi @LorisLombardo87 

Since you mentioned you're not interested in groups, did you make sure that you have the "Group creation" option set to OFF in your tenant settings ?
