Hi,
We have checked all the files related to krb and keytab, all files and
their permissions are good. But still updates are getting denied. I am
attaching the Krb5 Trace output also, please check and let me know.
tkey-gssapi-credential option also specified in the named.conf, but
still updated are denied.

Hello,
my first bet is missing tkey-gssapi-credential configuration statement
[1], followed by:
- or incorrect content of keytab,
- some file permission problem related to /etc/krb5.keytab, or
/var/tmp,
or /tmp,
- It's Red Hat so a SELinux denial might be a problem as well.
KRB5_TRACE environment variable might help with debugging, see "man
kerberos" and also check other environment variables and config files
listed there.
Given that you have a working system I suggest you compare all of the
above to find out what's the difference.
