Hello,
kadmind listens to both TCP and UDP ports 749 and 464 (four ports).
KRB5_TRACE=/tmp/a kpasswd prints:
[11482] 1600291290.023827: Sending DNS SRV query for
_kpasswd._udp.REALM.
[11482] 1600291290.023828: Sending DNS SRV query for
_kpasswd._tcp.REALM.
[11482] 1600291290.023829: No SRV records found
[11482] 1600291290.023830: Sending DNS URI query for _kerberos-
adm.REALM.
[11482] 1600291290.023831: No URI records found
[11482] 1600291290.023832: Sending DNS SRV query for _kerberos-
adm._tcp.REALM.
[11482] 1600291290.023833: No SRV records found
https://web.mit.edu/kerberos/www/krb5-latest/doc/admin/realm_config.html talks about _kerberos-adm._tcp and _kpasswd._udp, but not about
_kpasswd._TCP.
Please verify whether _kpasswd._TCP is used and document it.
Regards
Dilyan
