[keycloak-user] Problems with nextcloud integration: Duplicated Attributes in response

[Michael Meier]

hi all

When I (and also others) tried to use saml login from nextcloud over
keycloak, there is an error message about Duplicated Attributes. As far
as I could find out, it looks like the role Attribute appears more than
once.
According to the saml add on developper is intentionally does not
support double attribute, and keycloak should group the values.
See:

https://github.com/onelogin/php-saml/issues/223#issuecomment-309718760


So I'm wondering if that is a bug in keycloak or a missing feature, or
if I was just to stupid to find the corresponding setting ;-).

I'm not sure how I could post the keycloak saml client config I use.

thanks for any advice in that issue...

Michael
