[warning] K-1515: Object not found unknown user

  • Hi Forum,

    we are getting a lot of “[warning] K-1515: Object not found unknown user” messages in server.log.
    Kopano-admin -L gives a list of all groups and the defined “user” is listed there.

    Groups are often used for sending distributed mails to a group of users.
    I cant find a jira ticket or a forum post with K-1515 errors.

    i dont think this error should come up if the group is known to kopano. Can you implement in the next version that kopano is checking groups aswell not just users?


  • Our logs are flushed with these warnings as well. But i don’t know what these messages are meaning.

    K-1515: Object not found unknown user "user@domain.com": user@domain.com not found in LDAP

    I just replaced the mail adresses but this user is used in kopano and present in Active Directory…


  • Hello @darootler,

    if this user is a real user, try:

    kopano-admin --sync

    if this user is a group like my problem, you’ll need to wait for kopano update. - But i dont know if/when they implement to check for users AND groups


  • Use log_level = 0x200006 to get all the LDAP queries emitted into the log. You can then rerun the LDAP query with something like ldapsearch and see where/why it does not find the particular user.
