Question:

How to fix the issue, if you get alert about "Usermap data is stale" on Email security device.

Answer:

• When you configure the LDAP server, it pulls users/groups information from your LDAP server and stores that information on the usermap.xml file. This is an important file to keep updated for several reasons, but most importantly if you are using DHA Protection.
• DHA checks against usermap.xml file and treat an email as DHA if the recipients email is not found on the usermap.xml file. ( specially in case of new user addition on LDAP server or modification to existing users.)
• This alert indicates your Usermap.xml file has not been updated recently. By default, Usermap.xml is updated once an hour.
• You can configure the Usermap update interval (Usermap frequency) in the global configuration of LDAP configuration page.

To manually update the Usermap file you have follow the steps as mentioned below:

Step 1. Go to Manage | System Setup | Server | LDAP configuration page.

Step 2. Click on the server name, config page will open up,
Changes" on that page (even if you have not done any changes, this will trigger the ES to fetch new data from your LDAP server).

Users, Groups & Organizations | Users , click on "Refresh Users & Groups" button.

Restart Services" (this process will update the Usermap file once the services comes back up)

usermap data is stale"

Note: If saving your current LDAP configuration was unsuccessful, please make sure the following configuration are in place or working:

• The login credential to LDAP is correct.
• LDAP server is reachable from ES server.
• The LDAP port is configured correctly.
• LDAP query panel is configured correctly.
