This is a migration scenario, I see at least 2 ways:

a) some frontend (web?) app is built to proxy the user password to ldap
by performing a bind.

b) we provide a pam module smart enough to check the user status against
ldap if pam_kerb5 fails, and if it finds the user is in "upgrade" mode,
perform an (SSL protected) simple bind against the ldap server.
