Proposal: Support for 32 bit version numbers in keytabs

> Java uses the Version 1 format of the MIT keytab file.

Do you know if they seek to the next record length in processing a keytab
file - or do they simply fall into the subsequent record.

If the former - then we can make the change.

I found a copy of dce 1.2.2 at the opengroup site... it advances the
record. (i.e. we can add stuff at the end)...  So code based on this
codebase is ok.
