So I discovered that heimdal's kinit does not have a feature which
does this without password or keytab (which really astonished me,
because it has a lot of features allready). Look at this example:

Here I exeute a command "under heimdal kinit" (1) but if I try to do the
same with --renew (2) heimdal kinit ignores the command and renews the
tickets in my current cache instead.

1:

$ /usr/heimdal-1.2.1/bin/kinit h...@nada.kth.se sh -xc ' klist ; sleep 30 ; 
klist'
h...@nada.kth.se's Password: 
+ klist
Ticket cache: FILE:/tmp/krb5cc_O38B1t
Default principal: h...@nada.kth.se

Valid starting     Expires            Service principal
07/07/09 11:20:08  07/07/09 21:20:08  krbtgt/nada.kth...@nada.kth.se
07/07/09 11:20:08  07/07/09 21:20:08  a...@nada.kth.se
07/07/09 11:20:08  07/07/09 21:20:08  afs/pdc.kth...@nada.kth.se
+ sleep 30
+ klist
Ticket cache: FILE:/tmp/krb5cc_O38B1t
Default principal: h...@nada.kth.se

Valid starting     Expires            Service principal
07/07/09 11:20:08  07/07/09 21:20:08  krbtgt/nada.kth...@nada.kth.se
07/07/09 11:20:08  07/07/09 21:20:08  a...@nada.kth.se
07/07/09 11:20:08  07/07/09 21:20:08  afs/pdc.kth...@nada.kth.se


2:

$ /usr/heimdal-1.2.1/bin/kinit --cache=$KRB5CCNAME --renew sh -xc ' klist ; 
sleep 30 ; klist'
#no sh is run

Or is there another syntax that would do the trick? Seems I have to read the 
source....

Harald.
