• what causes user sync to deactivate a user?

    I am using DW User Sync to sync AD using LDAP to DW in the cloud version 7.4
    Works for most users just fine.  I have four users that get deactivated at each sync.  The logs just say that they are being deactivated but no reason for the action.
    They are in the same group as other users and I cannot find the unique thing about their accounts that would cause this.
