    Default external LDAP password caching

    Hi all,

    I have a Zimbra setup (5.0.16 GA Network Edition) with external LDAP Authentication. Everything works good so far.

    Today I noticed, that users who changed their password on the external LDAP can still login to the Zimbra Account
    using the old password (login with the new password works as well).

    Is this a Zimbra/LDAP cache feature? How could the max age of the cache be set?

    Regards
    Thomas

    This is documented behavior for Active Directory. Old passwords are still good for one hour. Other LDAP servers might behave similarly for similar reasons.

    Hi Rich,

    thanks a lot. You are probably right, as we are using AD as an external LDAP auth source... I did not know about this AD feature.

    Thumbs up

    Hey Guys
    The caching is done at Windows server level and a known feature/bug. you can refer to Microsoft article for more details Windows Server 2003 Service Pack 1 modifies NTLM network authentication behavior
