As long as the user has not logged in it is expected that the id command
doe not show the full list of groups. To see why the login fails it
would be good to know how you try to log in (I assume ssh) and which
authentication method is used (password, ssh key, Kerberos ticket).
Additionally the SSSD log files might be needed, most important here are
the logs from the PAM and PAC responders and the domain log.

For RHEL5 you need a special configuration for SSSD, call 'ipa-advise
config-redhat-sssd-before-1-9' for more details.
