How to change expired LDAP user password under linux?

  • 772

can somebody give an advice how to change the LDAP password already expired?

I have an LDAP user and the password for this user is expired:

# su user
You are required to change your password immediately (password aged)
su: Authentication token is no longer valid; new one required
(Ignored)

then I can change the password using 'passwd'. But if I try to login once again, the message still appears. If I try the ssh login, I also get the following message: "You are required to change your password immediately (password aged)"

Then I change the password. But if I try to login once again, the message remains...

Thank you in advance.

P.S. I have also tried:

user@server$ ldappasswd

Please enter your password: 
ldap_sasl_interactive_bind_s: Invalid credentials (49)
additional info: SASL(-13): user not found: no secret in database
linux

  1. You are missing a few attributes from your ldappasswd

    This is just an example

    ldappasswd -x -h <host> -D "<rootdn>" -w <rootdn_password> -s <new_password_for_user> "uid=user,ou=People,dc=example,dc=com"

    Probably you are using some policies (some of them can be kept in LDAP - for instance you got something like that in your LDAP server configruation)

    overlay ppolicy
ppolicy_default "cn=default,ou=policies,dc=example,dc=com"
ppolicy_use_lockout

    Some of them can be kept locally (look for moduleload ppolicy.la in LDAP server configuration).

    Probably you are also missing ability to allow users to change thier passwords without god's power. You can do it by resetting PAM or (easier way) to allow users to change thier userPassword attribute without authentication.

    access to attrs=userPassword
        by self write
        by anonymous auth
        by users none

access to * by * read

    Whenever you need more precise please let me know :)

  2. Are you using shadow* attributes on the server? If yes make sure shadowlastchange attribute is writable by the user(s), otherwise the userpassword attribute get updated and shadowLastchange remains un-changed, on next attempt, the client tools calculate password age using the old shadowLastChange value and think the password needs to be changed.
