I'm playing with google-authenticator libpam
https://code.google.com/p/google-authenticator/
It appears to be failing the "make test" on CentOS 5.9 32bit.
./pam_google_authenticator_unittest Testing base32 encoding Testing base32 decoding Testing HMAC_SHA1 Loading PAM module
Running tests, querying for verification code Testing failed login attempt Testing required number of digits Testing a blank response Test handling of missing state files Testing successful login Testing WINDOW_SIZE option Testing DISALLOW_REUSE option Testing RATE_LIMIT option Testing TIME_SKEW pam_google_authenticator_unittest: pam_google_authenticator_unittest.c:137: verify_prompts_shown: Assertion `num_prompts_shown == expected_prompts_shown' failed. Invalid verification code make: *** [test] Error 1
Playing with the code...
// Test TIME_SKEW option puts("Testing TIME_SKEW"); for (int i = 0; i < 4; ++i) { set_time((12000 + i)*30); char buf[7]; response = buf; sprintf(response, "%06d", compute_code(binary_secret, binary_secret_len, 11000 + i)); assert(pam_sm_open_session(NULL, 0, targc, targv) == (i >= 2 ? PAM_SUCCESS : PAM_SESSION_ERR)); verify_prompts_shown(expected_good_prompts_shown); }
Up to here works fine...
set_time(12010 * 30); char buf[7]; response = buf; sprintf(response, "%06d", compute_code(binary_secret, binary_secret_len, 11010)); assert(pam_sm_open_session(NULL, 0, 1, (const char *[]){ "noskewadj", 0 }) == PAM_SESSION_ERR); verify_prompts_shown(0);
This is where it fails.
The same code works correctly without error on CentOS 6.4 64bit.
Has anyone else managed to pass the tests on 5.9 32bit?
