As it happens we use pipes to Perl to manage Kerberos accounts from 
Plone: here is the core of a method that does all the work:

from popen2 import popen3

def krb_cmd(kmd, arg):
     krb_out, krb_in, krb_err = popen3(kmd)
     krb_in.write(arg)
     krb_in.write('\n')
     krb_in.close()
     out = krb_out.read()
     err = krb_err.read()
     krb_out.close()
     krb_err.close()
     res = (err,out)
     return res


kmd is the command I pipe to. arg is the arguments to that command.
krb_in is std_in to kmd, krb_out and krb_err are std_out and std_err to 
kmd, and I wrtie to krb_in and read from krb_err and krb_out.

Finally i return the results from std_err and std_out as a tuple of strings.

hope this helps.

BTW: Anyone knows of a real, working Python-Kerberos module?
