...the following error when trying to change passwords on my Samba 4.7 AD via LDAP: ``` ldap_exop_passwd(): Passwd modify extended operation failed: Extended Operation(1.3.6.1.4.1.4203.1.11.1) not supported ``` Is this feature (1.3.6.1.4.1.4203.1.11.1) still not supported? Also, I have tried setting dsHeuristics for iutem 9 (fUserPwdSupport) to 1 with: ``` samba-tool forest directory_service dsheuristics 000000001 ``` But there doesn't seem to be a way to get it to reset to "default value" (empty). Any ideas how I would do that? Thanks, Ben

...This feature has never been seen on Active Directory DCs, and Samba has not had a patch for this contributed. We would welcome such a feature, but note it would need to be quite carefully implemented and tested to ensure it honours all the appropriate ACLs. > Also, I > have tried setting dsHeuristics for iutem 9 (fUserPwdSupport) to 1 > with: > > ``` > samba-tool forest directory_service dsheuristics 000000001 > ``` > > But there doesn't seem to be a way to get it to reset to "default > value" (empty).

...ma,CN=Configuration,DC=x are showing up where they shouldn't be). This goes for the GC and non-GC ports. I have modified my schema and set isMemberOfPartialAttributeSet to true in order to make posix attributes available in the GC, as well as defaultHidningValue and showInAdvancedViewOnly, and dsHeuristics to enable anon access. I tried disabling anon access, but that didn't make any difference. Thanks, cs

In our current testing environment, we are using nslcd to get user and group information from the Samba4 LDAP server, using the last part of objectSid as uidNumber. The configuration is designed to pull down unixHomeDirectory and loginShell if they exist, but they default to standard values if they do not. nslcd on each machine binds to LDAP using a dedicated user account, nslcd-service, and

Hi, Is there any setting in smb.conf that prevents the AD enumeration like user, group or computer enumeration? We tried to follow different methods recommended by Microsoft for the AD. But they don't seem to work. Still using apps like powershell, we can still enumerate the users, groups etc. Best regards, Anantha Raghava
