Emmanuel Lecharny updated DIRSERVER-1882:
-----------------------------------------
Fix Version/s: (was: 2.0.0-RC1)
2.0.0-M15
> KertabEncoder.write() method should take into account the size of the entries
> list to determine the buffer size
> ---------------------------------------------------------------------------------------------------------------
>
> Key: DIRSERVER-1882
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1882
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: core
> Affects Versions: 2.0.0-M14
> Reporter: Wei Yan
> Fix For: 2.0.0-M15
>
>
> Currently {{KeytabEncoder.write()}} always allocate 512 bytes as the buffer
> size, and doesn't consider the entities list size.
> {code}
> ByteBuffer write( byte[] keytabVersion, List<KeytabEntry> entries )
> {
> ByteBuffer buffer = ByteBuffer.allocate( 512 );
> putKeytabVersion( buffer, keytabVersion );
> putKeytabEntries( buffer, entries );
> buffer.flip();
> return buffer;
> }
> {code}
> For each entity, {{KeytabEncoder.putKeytabEntry()}} allocates 100 buffer size.
> {code}
> private ByteBuffer putKeytabEntry( KeytabEntry entry )
> {
> ByteBuffer buffer = ByteBuffer.allocate( 100 );
> ......
> }
> {code}
> This mechanism fails when we create multiple principals in one keytab file.
> {{KeytabEncoder.write()}} method should take into account the size of entries
> list to determine the buffer size. And a reasonable max size (100 currently)
> per entry must be determined.
