kadm5 patch to add keytab authentication

Hi,

I'm Miles Davis, and I work in the Computer Science department at Stanford University. We've recently started using the kadm5 extension to replace some scary old code, and my summer research students (CCd) made some improvements that I'd like to submit, namely the ability to obtain tickets via keytab rather than password. If the extension needs a maintainer, I'm volunteering.

http://cf.stanford.edu/kadm5-csdcf.patch

kadm5.c:79 inserted php function declaration for kadm5_init_with_skey
kadm5.c:491-550 inserted php function kadm5_init_with_skey which mirrors kadm5_init_with_password, exchanging the password argument for a keytab argument and wrapping "kadm5/admin.h" function kadm5_init_with_password.
config.m4:62  removing reference to libdyn, which no longer exists


Thanks,
