Hi, I'm having problems connecting from a Mac OS X (v10.2) box to a Linux (Red Hat 9, kernel 2.4.23) box running Samba as a PDC. The Mac OS box is running Samba 2.2.3a (build 26), the Linux box running Samba 3.0.1. The problem seems to be the following: (this is a level 4 log, I think) [2004/01/13 10:41:18, 4] auth/auth_sam.c:sam_password_ok(227) sam_password_ok: Checking NT MD4 password [2004/01/13 10:41:18, 3] auth/auth_sam.c:sam_password_ok(243) sam_password_ok: NT MD4 password check failed for user epayne [2004/01/13 10:41:18, 3] auth/auth_winbind.c:check_winbind_security(79) check_winbind_security: Not using winbind, requested domain was for this SAM. [2004/01/13 10:41:18, 2] auth/auth.c:check_ntlm_password(312) check_ntlm_password: Authentication for user [epayne] -> [epayne] FAILED with error NT_STATUS_WRONG_PASSWORD [2004/01/13 10:41:18, 3] smbd/error.c:error_packet(94) error string = Invalid argument [2004/01/13 10:41:18, 3] smbd/error.c:error_packet(118) error packet at smbd/sesssetup.c(817) cmd=115 (SMBsesssetupX) NT_STATUS_LOGON_FAILURE Windows (NT 4.0, 98, 2000 and XP Pro) and other Linux boxes can connect fine, as did this Mac before I upgraded to 3.0.1 (2.2.8 definately on the server and Im pretty sure it worked with 3.0.0 as well). Is there some known incompatibility between 2.2.3a and 3.0.1, or is this a bug, or is there a known work-around, or should I supply more logs, and if so what level? I have a level 10 dump but it doesnt seem to have that much more than the dump above, apart from random lines... Incidentally I know I should upgrade to 2.2.8, is there any way of doing this without losing the integration with NetInfo and stuff - upgrade from Apple or whatever?
