Is this just the general rule (more than one krb5 == pain), or something
extra and specific to OpenMVS?
Because we do not install or rely on shared libraries for krb5 or ldap,
we avoid most of that pain. (They are just more items in the

Correct. I've made some notes in auth/kerberos/kerberos-notes.txt.
Separate to that, I've started to use Heimdal's ASN.1 compiler (which
doesn't rely on the rest of Heimdal) instead of our hand-done ASN.1.
I'm hoping to plug some SPNEGO memory leaks that way...
Frankly, moving to compiling against MIT will require a lot of work on
MIT, and doing it badly could jeopardise the whole Kerberos area in
Samba4. As such, I had hoped to push this off until after we have a
release out the door, when I hope we will have a final list of
requirements, and might have a chance of doing it 'well'.
(Samba3 has much less use of krb5, and has a very heavy weight of
compatibility glue around it's neck. In particular I don't want that
weight to kill the chance of getting a release out).
