> 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:
> {code:java}
> java.io.IOException: Unexpected octets len: 16716
> at org.apache.kerby.kerberos.kerb.KrbInputStream.readCountedOctets(KrbInputStream.java:72)

> {code}
> The part of the code which is responsible for this error is [https://github.com/apache/directory-kerby/blob/507c74bc3547e80b7102d3b7e5c753e67b60fb9a/kerby-kerb/kerb-util/src/main/java/org/apache/kerby/kerberos/kerb/keytab/Keytab.java#L199.] 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.
