similar to: Increasing database size limit

Hi Volker, First I apologize for very late reply. I did tests in the meantime... Trust relationships are the option we keep in mind. As trusts are for now bidirectional-full-trust they give us possibility to increase domain size. If we have to split our domain we will split in one domain for users and another for computers (meaning users' MS Windows computers as they need to be included into

Hi Volker, I have same behaviour here without enumerating users or groups. As soon as the DB increase too much (which is not too much, my tests months ago made Samba starting to hang on certains commands (ldapcmp, wbinfo -u...) around 40000 objects in Samba database. On DC wbinfo -u is hanging today after 10s. This on the 2 DC I tested (on 20 DC). As soon as wbinfo -u is launched RPC PID of

Hi all, Still playing with a big database (120k users, 150k computers) I tried to split my users into a lot of OUs. This increased the database size and I was not able to finish to add users into the DB because database file has reached 4GB size which seems to be the limit. First: am I right to say file /var/lib/samba/private/sam.ldb.d/DC=example,DC=com.ldb has a maximum size of 4GB? Secondly:

Hi. Does winbind has limitations with lots of users in domain? I'm compiled samba 4.3.1 and created 40 users, so winbind and getent works fine, but when created 26.000 users and "wbinfo -u" doesn't show users. On DC Member Server, "wbinfo -u" and "getent passwd" doesn't show users to. On log.wb-CORP appears: [2016/02/23 18:46:46.319393, 1]

I disabled client signing from the client side, via OS X's global nsmb.conf file: https://discussions.apple.com/message/30282470#30282470 The performance was back to over 600 MB/s, as compared to 60 MB/s with signing. It just seems a bit weird to me that Apple, in response to the Badlock bug, would have changed the OS X client default to something with such drastic performance implications,

Hello, is it possible to configure Samba that only check User+Password is OK on a Active Directory Server ´s ( No Domain Join of the Samba Server) ? Thanks Dennis

This was a test on debian Jessie with sernet samba 4.2.3. and the test was, "login" with a AD user on ssh. this worked, fine, but this i noticed later.

Hi Volker, Reaching to RedHat is not the option for me right now, could you please tell me are there any configuration parameters in smb.conf which will avoid issuing NULL or Anonymous connections or sessions.

Hi Everyone, I have Samba server 3.5.10 running on RHEL 5.8 platform and it has joined to our AD domain controller.

I would appreciate it if you can change the host value in the /etc/nsswitch.conf file from *hosts:* to *files wins dns * and try again by restarting the server, since the error occurs whenever I restart the server. However, If I change the host value which is *hosts: * in the /etc/nsswitch.conf file to *files dns wins *and restart the server everything runs perfectly, when the alignment of

The directory is small, it contains only one file. stat() takes 15ms and if I read 1000 files it sums to 15 seconds. So the issue is really that open file is synchronous.

All users and groups are local (passwd/groups) maintained. We only want to authenticate the users against the ldap server (openDJ). No Active Directory is used. But if I configure, there are a lot (to much) ldap
