PROBLEM: Password change not sync on slave

When I modify the password for a specific user on the MASTER, the password change is not propagated to all SLAVES.

Note: My MASTER is one of the site (out of 4) on my WPMU installation. Slaves are on single WP installation under sub-domains.

I have attached logs
