Name

Synopsis

/etc/krb.conf

Description

krb.conf contains configuration information describing the Kerberos realm and the Kerberos key distribution center (KDC) servers for known realms.

krb.conf contains the name of the local realm in the first line, followed by lines indicating realm/host entries. The first token is a realm name, and the second is the hostname of a host running a KDC for that realm. There can be multiple lines for a given realm; the servers are tried in order until an active one is found. The words admin server following the hostname indicate that the host also provides an administrative database server. For example:

ATHENA.MIT.EDUATHENA.MIT.EDU kerberos-1.mit.edu admin serverATHENA.MIT.EDU kerberos-2.mit.eduLCS.MIT.EDU kerberos.lcs.mit.edu admin serverThe

Kerberos configuration information can also be supplied using the krb.conf NIS map. If /etc/krb.conf is not found (or the requested information is not found in it), and the system is running NIS, then the information will be obtained from the NIS map. If neither the file nor the NIS map are found, then the Kerberos library will use the domainname (as returned by domainname(1M) ) as the Kerberos realm, and the host kerberos as the location of the KDC. There is no default for the admin server.

Note that every time krb.conf is modified, kerbd(1M) needs to be restarted.
