[krbdev.mit.edu #7412] Documentation__kdc.conf vs man kdc.conf, etc

[Greg Hudson via RT]

In any recent Kerberos release, the KDC and related programs (kadmind, 
kdb5_util, etc.) merge the contents of krb5.conf and kdc.conf, while 
other programs (kinit, klist, etc.) read only krb5.conf.  Any profile 
sections can appear in either file, or in both.

During the past year, we've been reorganizing the documentation of 
krb5.conf and kdc.conf to put KDC-related relations in the kdc.conf 
documentation and general-purpose relations in the other.  The man pages 
in the forthcoming 1.11 release should reflect what's currently on the 
web.

The [login] section is only used by the krb5-aware login program, which 
has been unbundled from the krb5 package into the krb5-appl package.  So 
we don't document it any more.

We do not have a particular recommendation for whether KDC-related 
plugin module registrations appear in kdc.conf or krb5.conf.  The 
[plugins] section is documented in krb5.conf because it is relevant to 
all Kerberos programs and not just KDC-related programs.
