Error description

  • Sametime Community server is using a Domino 853 Fixpack 6 LDAP
    server
    to perform LDAP authentication and name lookups.  As soon as
    Sametime Community server's directory assistance is set to
    point to the 853 Fixpack 6 LDAP server, the CPU usage on the
    ldap server spikes to 100% and
    contact lookups from Sametime timeout.  If the directory
    assistance is set to use a 853 FP5 based ldap server instead
    the issue is not experienced
    

Local fix

  • Reverted Domino LDAP server back to 8.5.3 fixpack 5

     This fix tracks the match status of sub-filters so that

     enabled by the INI parameter LDAP_COMPLEX_FILTER=1.
    

Problem conclusion

  • Complex LDAP queries fail because of search type mismatches.
     This fix tracks the match status of sub-filters so that
