compile pam_radius_auth.so on AIX 5.3

Hi Could someone already compile pam_radius_auth.so (1.3.17 or any other version) on AIX 5? I could compile the module but pam seems to ignore it completely. Other pam modules are working fine together with sshd. pam.conf: (...) sshd account sufficient /usr/lib/security/pam_radius_auth.so debug (...) /etc/raddb/server: (...) myserver:myport mysecret 3 Kind Regards
