Bug 643532 - Incorrect DNs sometimes returned on searches
    
    https://bugzilla.redhat.com/show_bug.cgi?id=643532
    
    Description: Some of the functions in ldbm_entryrdn.c uses
    static memory for reading data from the entryrdn index, where
    the static initializer should not have been used since the
    memory cannot be shared among threads.  This patch fixes it.
