similar to: Samba4 as AD, what password hash is used?

Hi, Thank you for this answer, unfortunately I was not able to re-hash password as they are hashed into LDB database. First I retrieved the hash: ldbsearch -H $sam '(cn=some user)' unicodePwd # record 1 dn: CN=some user,OU=Users Management,DC=ad,DC=example,DC=com unicodePwd:: COwwLgiqqaHRyhy4HxWp4A== This "unicodePwd" attribute comes from a quick search into "user"

Hi, We are (again) looking at syncing our samba AD to the azure AD cloud. I installed a win2016 server domain member server and set it up for syncing, including password hashes, so users can login azure/O365 using their on-prem passwords. We're using microsoft's latest tech: the new "Azure AD Connect cloud provisioning". We made sure to check "password hash sync".

Rowland, Can you test this: echo -n $(ldbsearch -H /var/lib/samba/private/sam.ldb -b 'dc=CHANGE_BASE' -s sub '(&(objectclass=user)(samaccountname=CHANGE_USERNAME))' unicodePwd |grep unicode |awk '{ print $NF }') | base64 -d -w 0 | iconv -t UTF-8 -f UTF-16LE The results are chinees characters. But if i put it in the example you showed, it shows the correct things.

hello list, What kind of hashing/encryption samba4 ADDC uses for user passwords? base64? Thanks! -- Elias Pereira

Hi, First some background: ================== I had a test environment which had two samba DCs (running v 4.8.0rc2) and 1 Windows Server 2008R2 DC. The samba DCs had been upgraded from v 4.6x and the secrets database was not encrypted (as far as I know). I decided to downgrade one of the samba DCs to v 4.7.4. On re-starting samba after the downgrade the log shows: ldb: unable to dlopen

Hai, just make a CSV file and import your users. this is the script i used. #!/bin/bash ## example ## display naam in AD wil be : Louis van Belle ( cat /home/samba/backup/users.csv | awk -F ";" '{system("/usr/bin/samba-tool user add "$5" --mail-address="$7" \ --given-name="$4" --surname=\""$3"\"

Hi all I am trying to create a webapp to allow users to change their own passwords in Samba4 (perhaps, also in AD), using LDAP(s). But when I try to modify the user password using this code: dn: ........ changetype: modify replace: unicodePwd unicodePwd: "Temporal2" I get this error: 0x32 (Insufficient access; error in module acl: insufficient access rights during LDB_MODIFY (50))

Thanks Rowland. That makes sense :-) BTW, Is the following code enough to change the password with python-ldap? con.sasl_interactive_bind_s("", sasl_auth) mod_attrs = [ (ldap.MOD_REPLACE, 'unicodePwd', new_password), (ldap.MOD_REPLACE, 'unicodePwd', new_password) ] con.modify_s('CN=%s,CN=Users,DC=lxc,DC=com % username, mod_attrs) Thanks! Regards, Norberto

A blank password should work yes, but I do not know if I can make is to put each user change password at next logon. I did not see this option in the ldif ... -- View this message in context: http://samba.2283325.n4.nabble.com/Import-USER-and-PASSWORD-Samba3-OpenLadp-TO-Samba4-tp4690180p4690214.html Sent from the Samba - General mailing list archive at Nabble.com.

I am building an application in Rails using ruby-net-ldap and I am trying to figure out how to change passwords in Active Directory. Does anyone have any experience with this using the ruby-net-ldap gem? I know that I remember seeing an example on the web somewhere that showed how to do this using the depot application from the Rails book but for the life of me I can''t find it again. :(

Hello I will try give you best answer what I can. - alma linux 9, fresh installation, for testing only in virtualbox - packages from Sernet, installad via YUM from oficial repo - installed version 4.18 (same on original linux) - moved backup from original server, /var/lib/samba + /etc/krb, /etc/default/samba, /etc/samba - original domain created if I remember on 4.15 or 4.16, then schema

hello, I use Samba 4.9.5 on Linux Debian 9. I want to extract users' passwords. A lot of passwords are ok, some are not. Example with a password returning an error : # ldbsearch -H /var/lib/samba/private/sam.ldb '(primaryGroupID=513)' userPrincipalName unicodePwd .... # record 494 dn: CN=XXX,CN=Users,DC=YYY,DC=ZZZ,DC=fr unicodePwd:: wXQvJaSkn0gvg1POsY9Icw== uidNumber: 5110

Thanks for getting back to me. Sadly I've not had the time today to attempt the reproduction. Can you, just to save me time, double-check if this happens on a server with the Samba 4.20 being a just from-our-tarball Samba and show the logs that gives?

Hello, I have a small test network with a Win2k8R2 DC. I've added a samba4 as second DC in this network. The join seems to run smoothly. But, after the join, this command: ldapsearch -LLL -x -H ldapi://%2Fvar%2Flib%2Fsamba%2Fprivate%2Fldap_priv%2Fldapi -b "dc=test,dc=dom" "(SAMAccountName=Administrateur)" returns some strange results: ? some attributes like unicodePwd

Hello, please check my progress I did it on the same virtual Centos 9 to avoid posibilities of differencies between original and new installed linux - backup /var/lib/samba storage - uninstalled sernet-samba - installed samba 4.20.0 from tar source code - location default /usr/local/samba - replaced files from /var/lib/samba to /usr/local/samba (to right location) - started samba - done -
