+Added to address RHBZ#1449689
+
+Original patch notes from <hhorak@redhat.com> follows:
+
+...
+
+In FIPS mode there is no md5 by default, unless declared it is specifically
+allowed. MD5 is used for non-crypto related things in MySQL (digests related
+to performance schema and table list), so it is ok to use MD5 there.
+
+However, there is also MD5() SQL function, that should still keep working,
+but users should know they should avoid using it in FIPS mode.
