I just did some testing here, and on my configuration (mod_auth_kerb without Basic authentication fallback), hitting enter at both the username and password prompts results in a successful connection with stock git. This makes sense, because with GSSAPI authentication, your ticket is tied to your username, so no explicit username is needed. If I turn on KrbMethodK5Passwd and try to push without credentials, I can confirm that git refuses, even if the correct password is set. It looks like libcurl really doesn't want to use Basic authentication if there's a "better" choice. Jean-Francois, do you have KrbMethodK5Passwd set to on (the default)? If so, you might try turning it off and forcing Kerberos authentication all the time. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
