I upgraded several machines from 10.3-stable to 11.1-release by doing the following: * Move from 10.3-stable custom kernel to 10.3-generic * upgrade 10.3-generic-stable to 11.1-release-p6 with freebsd-update After the update the following for files/links are missing: /usr/lib/libypclnt_p.a /usr/lib/libypclnt.a /usr/lib/libypclnt.so /usr/lib/libypclnt.so.4 pam_unix.so depends on those files and after a reboot you cannot log in anymore.
(In reply to Niels Kobschätzki from comment #0) Sorry, I upgrade from 11.0-stable to 11.1-release
