I just wrote some code to support openssl engines, tonight snapshot will
include it;

Using opensc pkcs11 engine using my softtoken:

./kinit --no-addr -C \
ENGINE:ENGINE=dynamic,PRE=SO_PATH:/sources/opensc/dest0.9.2/lib/opensc/engine_pkcs11.so,PRE=ID:pkcs11,PRE=LIST_ADD:1,PRE=LOAD,PRE=MODULE_PATH:/home/lha/src/cvs/soft-pkcs11/o/.libs/soft-pkcs11.so,CERT=/secure/lha/l.nxs.se/CA/lha.crt,KEY=slot_0 \


./kinit --no-addr -C ENGINE:CERT=/secure/lha/l.nxs.se/CA/lha.crt,KEY=slot_0 \

this in krb5.conf

	pkinit-openssl-engine = ENGINE=dynamic,PRE=SO_PATH:/sources/opensc/dest0.9.2/lib/opensc/engine_pkcs11.so,PRE=ID:pkcs11,PRE=LIST_ADD:1,PRE=LOAD,PRE=MODULE_PATH:/home/lha/src/cvs/soft-pkcs11/o/.libs/soft-pkcs11.so

my .softtoken.rc looks like this:

: lha@nutcracker ; cat ~/.soft-token.rc
# Separator is \t
# fields are id, label, cert file[, optional keyfile]
lha     Love's certificate      /path/lha.crt /path/lha-no-pw.key
anchor  L.NXS.SE CA     /path/CA/ca.crt

It all failes with

kinit: krb5_get_init_creds: Can't decrypt key: error:2A008404:PKCS11 library:PKCS11_rsa_decrypt:Not supported

because opensc doesn't implement rsa encryption/decryption in their openssl
pkcs11 engine module, that shouldn't be too hard to add.

I also updated http://people.su.se/~lha/patches/heimdal/pkinit/ to explain
what all the options mean.
