This is because the "auth_request" directive doesn't support 
variables, and also doesn't support request arguments.

Try this instead:

    location /imaadmin/ {
        auth_request /sso/validate;
        ... proxy_pass ...
    }

    location = /sso/validate {
        set $args SSOID=$ssoid_cookie&a=imaadmin;
        ... proxy_pass ...
    }
