 subject: kdc_tcp_ports not documented in kdc.conf.M
 target_version: 1.8.2
 tags: pullup

 The kdc.conf setting kdc_tcp_ports was not documented in kdc.conf.M,
 though it was documented in doc/admin.texinfo.  Copy text from there
 for now.  The setting defaults to an empty string at the moment,
 causing the KDC to not listen on TCP by default, confusing some users.
 Changing this behavior is a separate issue.
