You aren't invoking them correctly - you need to pass the security
context of the login process as the second argument, as I showed.

For example, on Fedora, we have:
$ ./getconlist user_u system_u:system_r:local_login_t:s0
user_u:user_r:user_t:s0
$ ./getseuser root system_u:system_r:local_login_t:s0
$ ./getseuser root system_u:system_r:local_login_t:s0
seuser:  unconfined_u, level s0-s0:c0.c1023
Context 0	unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

Omit the :s0 if you don't have MLS enabled in your policy.
