  • Closed as program error.

Error description

  • While accessing LDAP data, KXCRC_UNKNOWN_OBJECT error occurs
    with suberror KXMRC_UNEXPECTED_CHANGES: Unexpected changes in
    Roma configuration.
    

Local fix

  • 1) LDAP cache refresh can be disabled by setting KXCCTIME
    environment variable to a big value.
    For example, 864000 will disable LDAP cache refresh for 10 days
    and the problem will not happen 10 days.
    
    2) Use LDIF as a backup if CASP can't connect LDAP for some
    reason. LDAP content can be exported into LDIF and LDIF URL
    added to the KXCDIR, for example:
    
    KXCDIR=ldap://hoc08wuw05:389/cn=RomaContext,dc=Context,dc=Roma,d
    c=candle
    ,dc=com;file:////mydir/my.ldif
    

Problem summary

  • When CASP needs some LDAP data, cannot find it in the LDAP
    cache, trys to refresh the cache, and the LDAP server is
    unavailable at that time, KXCRC_UNKNOWN_OBJECT error occurs with
    suberror KXMRC_UNEXPECTED_CHANGES: Unexpected changes in Roma
    configuration.
    

Problem conclusion

  • Added reconnection logic to some functions accessing LDAP
    server, new constants LDAP_SEND_ERROR and LDAP_RECV_ERROR for
    clearer identification of LDAP server connection errors,
    improved handling of LDAP server connection errors.
    
    If KXM ILS LDAP cache cannot contact the LDAP server, error
    KXCRC_LDAP_SEARCH_FAILURE is raised instead of
    KXMRC_UNEXPECTED_CHANGES to describe the situation more clear.
