Ticket #47746 - ldap/servers/slapd/back-ldbm/dblayer.c: possible minor problem with sscanf
    
    Description: Warning in read_metadata (dblayer.c):
    > sscanf(thisline,"%[a-z]%c%s",attribute,&delimiter,value);
      (warning) scanf without field width limits can crash with huge input data.
    Adding the size of the buffer to the sscanf format.
    
    Thanks to dcb for reporting the bug and fix.
