k5identity
.K5LOGIN(5) File Formats Manual .K5LOGIN(5)
NAME
.k5identity - Kerberos V5 client principal selection rules
DESCRIPTION
The .k5identity file, which resides in a user's home directory, contains a list of rules for selecting a client principals based on the
server being accessed. These rules are used to choose a credential cache within the cache collection when possible.
Blank lines and lines beginning with '#' are ignored. Each line has the form:
principal field=value ...
If the server principal meets all of the field constraints, then principal is chosen as the client principal. The following fields are
recognized:
realm If the realm of the server principal is known, it is matched against value, which may be a pattern using shell wildcards. For host-
based server principals, the realm will generally only be known if there is a domain_realm section in krb5.conf with a mapping for
the hostname.
service
If the server principal is a host-based principal, its service component is matched against value, which may be a pattern using
shell wildcards.
host If the server principal is a host-based principal, its hostname component is converted to lower case and matched against value,
which may be a pattern using shell wildcards.
If the server principal matches the constraints of multiple lines in the .k5identity file, the principal from the first matching line is
used. If no line matches, credentials will be selected some other way, such as the realm heuristic or the current primary cache.
EXAMPLE
The following example .k5identity file selects the client principal alice@KRBTEST.COM if the server principal is within that realm, the
principal alice/root@EXAMPLE.COM if the server host is within a servers subdomain, and the principal alice/mail@EXAMPLE.COM when accessing
the IMAP service on mail.example.com.
alice@KRBTEST.COM realm=KRBTEST.COM
alice/root@EXAMPLE.COM host=*.servers.example.com
alice/mail@EXAMPLE.COM host=mail.example.com service=imap
