I'm trying to validate if a user is part of a particular group, then grant access using lua-resty-openidc with OpenResty. Following Chris Blanton's advice here: I added memberOf to the profile scope in OpenID Connect > Scopes > profile. My OpenResty config is set to return openid email profile. Profile scope works fine when I validate with the user's email ( I tried doing this in my OpenResty config: ``` local ADMIN_GROUP = '60B7' if res.user.member_of ~= ADMIN_GROUP then ngx.exit(ngx.HTTP_FORBIDDEN) end ``` However, I'm getting HTTP FORBIDDEN even though my user is in the default Gluu Manager Group, which 60B7 is the INUM by default.

It turns out res.user.member_of returns the full CN, not just the inum. Also, since res.user.member_of returns a table instead of a string, I ended up creating a for loop to iterate through res.user.member_of to match on **inum=60B7,ou=groups,o=gluu** If it match hit, then I made OpenResty authorize resource.

I don't recommend using the DN of the group in your code. You might want to check out a video I recorded about using RBAC with OAuth.
