[-s string | --ccache=string] [-s string | --server=string] [-c string | --client=string] [-k string | --keytab=string] [-5 | --krb5] [-A | --add] [-R | --referral] [-e integer | --expire-time=integer] [-a string | --client-address=string] [-t string | --enc-type=string] [--session-enc-type=string] [-f string | --ticket-flags=string] [--verbose] [--version] [--help] |
DESCRIPTION
The
kimpersonate program creates a "fake" ticket using the service-key of the service and stores it in the given (or default) ccache. This is useful for testing. The service key can be read from a Kerberos 5 keytab or AFS KeyFile. Supported options:
-
--ccache=string
-
ccache into which to store the ticket
-
-s string, --server=string
-
name of server principal
-
-c string, --client=string
-
name of client principal
-
-k string, --keytab=string
-
name of keytab file
-
-5, --krb5
-
create a Kerberos 5 ticket
-
-A, --add
-
don't re-initialize the ccache, instead add the ticket to an existing ccache.
-
-R, --referral
-
simulate a referrals-based KDC client by storing two entries, one with the empty realm for the service principal name.
-
-e integer, --expire-time=integer
-
lifetime of ticket in seconds
-
-a string, --client-address=string
-
address of client
-
-t string, --enc-type=string
-
encryption type (defaults to "aes256-cts-hmac-sha1-96")
-
--session-enc-type=string
-
session encryption type (defaults to enc-type or "des-cbc-crc" for afs service tickets)
-
-f string, --ticket-flags=string
-
ticket flags for krb5 ticket
-
--verbose
-
Verbose output
-
--version
-
Print version
-
--help
-
FILES
Uses /etc/krb5.keytab, and /usr/afs/etc/KeyFile when available and the -k option is used with an appropriate prefix.
EXAMPLES
kimpersonate can be used in
samba root preexec option or for debugging.
kimpersonate -s host/hummel.e.kth.se@E.KTH.SE -c lha@E.KTH.SE -5 will create a Kerberos 5 ticket for lha@E.KTH.SE for the host hummel.e.kth.se if there exists a keytab entry for it in
/etc/krb5.keytab.
In combination with the ktutil command, this is useful for testing. For example,
ktutil -k tkt add -p host/foo.test@TEST -V2 -e aes256-cts-hmac-sha1-96 -r
kimpersonate --cache=tcc -s host/foo.test@TEST -c jdoe@TEST -k tkt --referral
