[Samba] Allow self password change using LDAP(s) with Samba4
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: "Temporal1" - add: unicodePwd unicodePwd: "Temporal2" Then I get this error: #!ERROR [LDAP: error code 53 - 00002035: setup_io: it's not allowed to set the NT hash password directly'] The ldapmodify are executed using the self user credentials, i wouldn't like to use the administrator account. Is this possible? Do I have to change some settings in Samba4?

Hi Juan, you can use the 'kpasswd' utility: kpasswd user at YOUR.REALM It can be run as unprivileged user. It first prompts you for your old password and the twice for the new password.

[Samba] Allow self password change using LDAP(s) with Samba4
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)? 2016-01-07 10:12 GMT+01:00 Roel van Meer <roel at 1afa.com>:> Hi Juan, > > you can use the 'kpasswd' utility: > > kpasswd user at YOUR.REALM > > It can be run as unprivileged user. > It first prompts you for your old password and the twice for the new > password. > > Cheers, > > Roel > > > > Juan Asensio Sánchez writes: > > 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).
