test049, test050, test053 in HEAD now fail

test049 fails with invalid DN "cn=Ursula Hampster,ou=Alumni Association,ou=People,dc=example,dc=com" in the consumer because core.schema with 'ou' and 'dc' is not loaded.

test050 similarly fails on "dc=example,dc=com".

test053 also fails, i have not checked why. Like test050 it keeps waiting for syncrepl to receive changes, then gives up.

If it makes a difference, my configuration is ./configure --enable-dynamic --enable-modules --enable-dynamic --enable-dynacl --enable-aci --enable-crypt --enable-lmpasswd --enable-modules --enable-spasswd --enable-rlookups --enable-slapi --enable-backends=mod --disable-ndb --disable-sql --enable-overlays=mod
