> When using to read principal from a keytab file generated by a heimdal-kdc
> (version 7.5.0), it is throwing error because of miss-calculation of number
> of bytes read for an entry. The error is as follows:

> Here, we are trying to calculate the number of bytes read for an entry. But
> we are not considering the number of bytes denoting the size of an entry,
> which should be excluded from the calculation of bytes read for an entry.
