similar to: Workstation authentication and authorization failed event

Hello,     I recently upgrade Samba to 4.7.0 and enabled the Authentication and Authorization audit support. One of the first events I see is from a disabled user account.

Hai,   Im setting up a new proxy and im testing a bit around. Goal is, get everyting working with minimal changes to the system.   Setup: Debian 8 with NFS nfsv3 and v4 (krb) automounts,  winbind 4.5.3 , squid 3.5.24 (with ssl support) Which is basicly a copy of my other proxy but a new install with more systemd and less packages used.   Working: -          ssh logins with AD users.

Just to update this, I'm going to upgrade to samba4 but it won't be for a few days yet, I'll keep this thread updated with what happens.

Hai Paul,   hmm, i think its time.. to upgrade your samba.   I dont think the other krb5.conf options work, but you might give it a try. See man krb5.conf, where i took it from. add /change in krb5.conf  [kdc] tgt-use-strongest-session-key = BOOL svc-use-strongest-session-key = BOOL preauth-use-strongest-session-key= BOOL use-strongest-server-key = BOOL encode_as_rep_as_tgs_rep = BOOL   BOOL

No, no idee, but really, upgrade to samba, best option, in my opinion. If thats not possible, it happens.. A timeout option can be set in krb5.conf for example : kdc_timeout = 5000 You have these for krb5.conf to try out also. the complete list. des-hmac-sha1 DES with HMAC/sha1 (weak) aes256-cts-hmac-sha1-96 aes256-cts AES-256 CTS mode with 96-bit SHA-1 HMAC

Just saw that, as well. After running the commands to enable SMB2 & SMB3 and rebooting...no luck. Will keep searching for other registry settings.

When I search for "smb2", I get nothing in my log file for the NT1 limited system. If it is a workstation issue, that would be great. I'll search around for what settings to change. Maybe SMB2 was inadvertently disabled. Thanks for all of your help on this! On Tue, Apr 19, 2016 at 3:20 PM, lingpanda101 at gmail.com < lingpanda101 at gmail.com> wrote: > On 4/19/2016 3:11

I am accessing the new member server. All my other servers are still on 3.6.x. Both settings are set to "default". Will look at logs now. Thanks!

Hi, I'm hoping to find out whether R, or an R add-on, can generate a particular type of graph. And, more basically, whether such a type of graph even makes sense. I'm looking for something resembling both a column chart and a bar chart, where the basic visual "unit" is a solid rectangle of color that can be extended either horizontally, vertically, or both. The data that

After reviewing logs I found that my previous assumption was wrong. Situation: - i'm trying to start live migration from hyper-v host A (BMSRV4-HYPERV) to hyper-v host B (BM-SRV-5) from host B (logged in as user from DOMAIN ADMINS group). Kerberos constrained delegation is set in accordnance to microsoft instructions with proper SPN's set (well, proper as in with the workaround I

> I do not understand why you are doing this, for kerberos to work correctly, you need to be able to find everything easily and everything must be using the same time. So, you need kerberos, a dns server and an ntp server and if you want more than authentication, you need a fileserver. OH look, I just described Active Directory ? Not saying you cannot get this setup to work, but why are

Hi, I have just upgraded our Samba 4.1 AD servers to 4.2.2. Our AD was previously run on win2k3 and had configuration for account lockout after 3 bad passwords. This lockout obviously did not work after migration to 4.1 After the upgrade to 4.2.2 the lockout started working again, almost as expected. The current settings are Password complexity: on Store plaintext passwords: off Password

Hai, You may need to add the the following in krb5.conf [libdefaults] allow_weak_crypto = true ; for Windows 2003 ; default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 ; default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 ; permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 ; for Windows 2008 with AES default_tgs_enctypes = aes128-cts-hmac-sha1-96

Hi, I'm trying to track random account lockouts on the domain. Is there any recommendations for log level or log handling that let me see what machines/servers are locking the account? I'm using samba 4.5.5. as a DC (3 DCs). My current logging settings are: logging = syslog log level = 1 auth:5 passdb:5 winbind:5 Att, Vinicius
