Opened: Feb 14, 2020
Severity: 3-Major

Symptoms

There are intermittent auth failures when accessing the BIG-IP administration interfaces via SSH or the GUI.

Impact

There might be intermittent remote-auth failures.

Conditions

-- Remote LDAP auth is configured. -- An idle timeout RST is received on the LDAP connection before the configured auth LDAP idle-timeout expires. This RST might be generated by tmm (if the connection to the LDAP server is via a defined VLAN), some other intervening device on the network, or from the LDAP server itself (depending on its connection time limit).

Workaround

Set the auth ldap idle-timeout to a smaller value, for example, via tmsh: modify auth ldap system-auth idle-timeout 299

Fix Information

None
