Kerberos Authentication Support help

[Anilkumar.Palahanumanthrao@wellsfargo.com]

Please see below.

Also echo "password" | /opt/boksm/bin/kinit userid is prompting for password, which I is not expected. I want the command to take  password and login directly. Can you help ?

$ which kinit
/opt/boksm/bin/kinit
$
$ which klist
/opt/boksm/bin/klist
$ cd /opt/boksm/bin/
$ clear
$ ls -lrt

Anil,

This is not really "support" more than a community discussion list (for your information).

Do a 'which kinit' to verify your proper path to the kinit command on the distro you are on...

This works, but realize the path /opt/boksm/bin/kinit is not valid (by default) on linux...

for example:

[12:50 root at admin1 ~] > which kinit
kinit is /usr/bin/kinit
[12:50 root at admin1 ~] > kdestroy
[12:50 root at admin1 ~] > klist
klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_0)
[12:50 root at admin1 ~] > echo "Password1" | /usr/bin/kinit tgrayson at AD.EXAMPLE.COM<mailto:tgrayson at AD.EXAMPLE.COM>
Password for tgrayson at AD.EXAMPLE.COM<mailto:tgrayson at AD.EXAMPLE.COM>:
[12:50 root at admin1 ~] > klist -ef
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: tgrayson at AD.EXAMPLE.COM<http://AD.EXAMPLE.COM>

Valid starting     Expires            Service principal
10/06/16 12:50:40  10/06/16 22:51:32  krbtgt/AD.EXAMPLE.COM<http://AD.EXAMPLE.COM>@AD.EXAMPLE.COM<http://AD.EXAMPLE.COM>
                renew until 10/13/16 12:50:40, Flags: FRIA
                Etype (skey, tkt): aes256-cts-hmac-sha1-96, aes256-cts-hmac-sha1-96

Is this MIT's krb5 or Heimdal's?  What version?
