Hello all, Currently running a pair of FortiMail VM02 5.4.0 GA. The
cluster is a config master/slave but it tends to go out of sync. diag
sys ha showcsum will show a csum mismatch and when I check closer some
entries will be mismatched e.g. FML1:917:...
One thing to check and which was causing the issue for us. If you are
using an LDAP profile for authentication, it needs to be present in all
rules, even rules that don't need it, otherwise it did not work and
causes an error when accessing webmail.
