search for: unicodepwd

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)) If I change the code, deleting the old password, and adding the new one: dn: ........ changetype: modify delete: unicodePwd unicodePwd: "Te...

Hi Thanks all for your responses. The users can now change their own password adding and removing the unicodePwd attribute, using the correct method to generate the password value. Now, I have a problem, because the users who have the option to force to change the password in the next login checked, can't bind to the LDAP server in order to change their password. Is there any way to do this, using LDAP(s...

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" class: ldbsearch -H $sam -b 'CN=SCHEMA,CN=CONFIGURATION,DC=AD,DC=EXAMPLE,DC=COM' '(&(...

...d: replace userPassword: newPassword modifying entry "CN=John Smith,cn=Users,DC=domain,DC=com" modify complete This seems to work, but does not affect user in any matter. As far as I managed to find out, is that userPassword is not native Active Directory attribute. You must use unicodePwd attribute instead. But then I get to another problem: dn: CN=John Smith,cn=Users,DC=domain,DC=com changetype: modify replace: unicodePwd unicodePwd: newPassword ldapmodify -v -c -a -f filename.ldif -H\ ldaps://server.domain.com -D\ administrator at domain.com -W ldap_initialize( ldaps://server....

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 userPrincipalName: XXX ... ok. Then, I convert the password from utf-16 to hex : $ echo 'wXQvJaSkn0gvg1POsY9Icw==' | base64 -d -w 0 | hexdump -e '/1 "%02X"' C174...

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. :(

hi trying to create a user with ldap from a remote server. The user is created successfully. I'm failing setting the initial password. Setting the unicodePwd with kerberos administrator credentials with ldbmodify and the ldif below results in "00002035: setup_io: it's not allowed to set the NT hash password directly". searching the web I've found s4 mailinglist entries telling "do not set unicodePwd with ldap". this KB...

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.

...create the user in such a way that samba4 is happy with it, but I'm unable to set an initial password for the user. I've tried using a template user that has a known password and then duplicating that users nTSecurityDescriptor, but that doesn't seem to work. I've tried creating a unicodePwd entry with the following code: my $charmap = Unicode::Map8->new('latin1') or die $!; my $unipwd = $charmap->tou(qq{"$passwd"})->byteswap()->utf16(); But that doesn't seem to work either. I was wondering if anyone working with samba4 could recommend a way...
