KC 8.7.5 with LDAP and K-1515 warnings?



  • Hi, the VM is up-to-date CentOS 7.6 with KC 8.7.5 and OpenLDAP 2.4.44 using a hosted setup with LDAP as the source for the hosted domains. Periodicaly I see the following in the server.log:

    Tue Sep 10 19:00:07 2019: [warning] K-1515: Object not found unknown user "example.org": example.org not found in LDAP
    

    and the OpenLDAP logs show this query:

    sep 10 19:00:05 kopano.lab.thuis slapd[6213]: conn=1007 op=4934 SRCH attr=objectClass kopanoSharedStoreOnly kopanoResourceType kopanoSecurityGroup uid uid ou cn cn modifyTimestamp
    sep 10 19:00:05 kopano.lab.thuis slapd[6213]: conn=1007 op=4934 SEARCH RESULT tag=101 err=0 nentries=6 text=
    sep 10 19:00:05 kopano.lab.thuis slapd[6213]: conn=1007 op=4935 SRCH base="ou=example.org,ou=hosted,dc=kopano,dc=ldap" scope=2 deref=0 filter="(&(|(objectClass=kopano-user)(objectClass=kopano-contact))(|(!(objectClass=*))(objectClass=*)))"
    sep 10 19:00:02 kopano.lab.thuis slapd[6213]: conn=1001 op=5307 SRCH base="ou=hosted,dc=kopano,dc=ldap" scope=2 deref=0 filter="
    

    Anyone know what’s causing these queries and how to fix the error? Thanks!



  • What i would do here.

    Trace/get all logs but use the date and time stamps first.
    Collect all logs around that time of you server, with max ~5 min diff.
    Then check for the domain name in these logs.

    in that example the user and domain, these do exist on your server?

  • There should be a objectClass: kopano-company on the example.org object.



  • @thctlo Thank you for your suggestion. I think I figured it out (see below).



  • @jengelh said in KC 8.7.5 with LDAP and K-1515 warnings?:

    There should be a objectClass: kopano-company on the example.org object.

    @jengelh Thank you for your suggestion. example.org has objectClass: kopano-company. I found the following commit that (from reading it) may fix my issue:

    Mart van de Sanden committed a53150f9e7b 18 Jun 2019
    libserver: fix incorrect warning message on resolveUserStore

    https://stash.kopano.io/projects/KC/repos/kopanocore/commits/a53150f9e7b22a187dbc1de1914ca0332a490309#provider/libserver/ECUserManagement.cpp

    AFAICT it’s not in the kc-8.7 branch. Any chance it could be added to the kc-8.7 branch too for 8.7.6?
    I’ll add that commit to my 8.7.5 build and test.



  • Update: 8.7.5 with commit a53150f9e7b22a187dbc1de1914ca0332a490309 no longer shows the K-1515 warnings :-)



  • Done. ~~~~
