Hi,

There appears to be inconsistency between man kdc.conf and http://web.mit.edu/kerberos/krb5-current/doc/krb_admins/conf_files/kdc_conf.html with respect to the sections allowed in kdc.conf.

man kdc.conf says:

--8<--

       The following sections are currently used in the kdc.conf file:

       [kdcdefaults]
              Contains parameters which control the overall behaviour of the KDC.

       [realms]
              Contains subsections keyed by Kerberos realm names which describe per-realm KDC parameters.
-->8--

While http://web.mit.edu/kerberos/krb5-current/doc/krb_admins/conf_files/kdc_conf.html says:

--8<--

The kdc.conf file may contain the following sections:

[kdcdefaults]	Default values for KDC behavior
[realms]	Realm-specific database configuration and settings
[dbdefaults]	Default database settings
[dbmodules]	Per-database settings
[logging]	Controls how Kerberos daemons perform logging

-->8--

Given the above, we can see that web.mit.edu states three additional sections are permitted in kdc.conf that man does not list. 

Additionally, with respect to krb5.conf, http://web.mit.edu/kerberos/krb5-current/doc/krb_admins/conf_files/krb5_conf.html says:

The krb5.conf file may contain the following sections:

[libdefaults]	Settings used by the Kerberos V5 library
[realms]	Realm-specific contact information and settings
[domain_realm]	Maps server hostnames to Kerberos realms
[capaths]	Authentication paths for non-hierarchical cross-realm
[appdefaults]	Settings used by some Kerberos V5 applications
[plugins]	Controls plugin module registration

If the sections for kdc.conf and krb5.conf, as given by web.mit.edu, are taken as a set, it seems neither file is allowed to have the [login] section.

Finally, with respect to kdc.conf, is it recommended to put the [plugins] section in krb5.conf instead of kdc.conf on a KDC, as implied by web.mit.edu in the above URLs?

Thanks for your time.

Blake
