similar to: Samba authentication logs

This may have been asked before, but I can't find it. I am getting repeated external attempted to log into our AD/DC (running Samba 4.4.14). In /var/log/samba/log.samba I get entried like: 2017/09/19 05:02:25.562957, 2] ../source4/auth/ntlm/auth.c:430(auth_check_password_recv) auth_check_password_recv: sam_ignoredomain authentication for user [HPRS\333] FAILED with error

I used to also get related log messages of the form: auth_check_password_send: Checking password for unmapped user [HPRS]\[mark]@[ROVER] auth_check_password_send: mapped user is: [HPRS]\[mark]@[ROVER] but now all I get is the auth_check_password_recv in the log. Perhaps the change is due to an upgrade to Samba, or perhaps a change I made to my smb.conf log options? (see log config in my

Hi, Since I really would like some more info (specifically: remote ip address) to be logged with failed password attempts, I have tried to edit the samba source code. :-) Anyway, I changed in source4/auth/ntlm/auth.c > if (tevent_req_is_nterror(req, &status)) { > DEBUG(2,("auth_check_password_recv: " > "%s authentication for user [%s\\%s] " >

I am running Samba Version 4.1.23 as an AD/DC on Linux Slackware64 14.1. I am logging samba messages to /var/log/samba/log.samba with logging set to the following in smb.conf: log level = 2 passdb:5 auth:10 winbind:2 lanman:10 I have a script that scans this logfile for message like the following: auth_check_password_recv: sam_ignoredomain authentication for user [HPRS\thisuser] FAILED with

I've setup samba4 to authenticate against a separate LDAP server. I can ssh to my server but attempts to login to a windows7 member server using the ldap domain are not working. Relevant errors: [2014/07/18 06:46:28.177400, 3] ../source4/auth/ntlm/auth.c:270(auth_check_password_send) auth_check_password_send: Checking password for unmapped user [ldapdom]\[user]@[win7host]

I tried creating the logfile /var/log/samba/.log.samba.%m and restart samba. What it did was immediately create separate log files for each currently attached workstation:

Hi guys, about a one or two weeks ago I've updated my samba to v4.1.7 which might or might not relate to the problem at hand. However lately we've seen some issues with users not able to login to workstations (win 7). Windows servers (2008 r2 and newer) were also affected. Sometimes one or two reboots would solve this problems, on few occasions I had to rejoin the computer account to the

Hi, In the past (2 months ago) : I have two AD Domain under Samba 4.1 : A and B. I war able to  connect a share in A from B. Now (after upgrade) : I have a W2016 domain (B) and a Samba 4.6 domain (A) but I can't connect a share in A from B. The user from B which try to connect the share in A has the same login in the two domains. So since the upgrade I don't have the same behavior

Hi, I have been having issues with NTLMv2 on newly provisioned domains, using Samba 4.1 from backports on Debian Wheezy. Everything seems to be working fine, except for NTLMv2 authentication with Squid and "ntlm_auth" on newer Windows versions. If I set "Lmcompatibility" down on the Windows PCs, then authentication works, but that is temporary workaround at best. I have

New to linux and new to Samba so any direction in troubleshooting would be helpful. Here is what I have so far. Within a half an hour of a reboot of the server my cpu reaches high numbers and becomes slow to respond on all actions. With my limited understanding I have used vmstat to observe the system. I noticed is that the numbers of forks grows from 1-2k to 43k within 30 minutes after reboot. I

Hi again, I just started to debug things on the samba4 side: When trying to mount the Windows NFS share, I get the following error on the samba4 dc (just grepping for nfs in the logs): auth_check_password_send: Checking password for unmapped user [S5DOM.TEST]\[nfs/nfsclient.mydom.test]@[] map_user_info_cracknames: Mapping user [MYDOM.TEST]\[nfs/nfsclient.mydom.test] from workstation []

Hi, As I configured the Roaming profiles under linux, it more or less generate an abnormal operation (in less than 2 mins) if I add/copy some files to the home directory. But for Windows XP and Windows 7 is running smoothly and it generates folders at the Samba4 server location with corresponding users. e.g. Administrator (for XP), and Administrator.V2 (for Win7/2008) based on my observations.
