Depends upon your implementation, of course.

OpenLDAP 1.x (and U-Mich LDAP 3.3) have support authentication using
Kerberos IV.

OpenLDAP 2.x (currently in beta) has supports SASL using the
Cyrus SASL implementation.  Cyrus SASL supports plugins for
GSSAPI which is compatible with Heimdal (in fact, this is what
I am currently using).

OpenLDAP 2.x SASL/EXTERNAL(TLS) support is under development is
based upon OpenSSL.  I am not sure if OpenSSL supports GSSAPI
authentication (RFC2712), but this would another method of
authenticating using your Kerberos V credentials once we complete
our implementation of SASL/EXTERNAL.
