NAME

kimpersonate – impersonate a user when there exist a keyfile or KeyFile

SYNOPSIS

kimpersonate [-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/[email protected] -c [email protected] -5 will create a Kerberos 5 ticket for [email protected] 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
