Bug Description: Slapi_ct_memcmp expects both inputs to be
at LEAST size n. If they are not, we only compared UP to n.
Invalid migrations of passwords (IE {CRYPT}XX) would create
a pw which is just salt and no hash. ct_memcmp would then
only verify the salt bits and would allow the authentication.
This relies on an administrative mistake both of allowing
password migration (nsslapd-allow-hashed-passwords) and then
subsequently migrating an INVALID password to the server.
Fix Description: slapi_ct_memcmp now access n1, n2 size
and will FAIL if they are not the same, but will still compare
n bytes, where n is the "longest" memory, to the first byte
of the other to prevent length disclosure of the shorter
value (generally the mis-migrated password)

389-ds-base (1.4.0.21-1) unstable; urgency=medium
* New upstream release.
* Run offline upgrade only when upgrading from versions below 1.4.0.9,
ns-slapd itself handles upgrades in newer versions.
* rules: Actually install the minified javascript files. (Closes:
#913820)
