Does BIG-IP use TMM route-table to reach LDAP Servers for auth?

I'm trying to setup LDAP Authentication on a BIG-IP. This is the first time I do this, and it seems the BIG-IP cannot reach the LDAP server. ldapsearch form CLI return "Can't connect to LDAP Server (-1)"

 

I suspect a routing problem. I can ping the LDAP server if I specify the MGMT interface as source. If I dont, the ping fails. TMM only has a default route point towards the internet, that's away from the LDAP server.

 

Does the BIG-IP use the TMM route-table to reach LDAP Auth servers? Otherwise I would at least get a response, right?

  • Hello, you have to add a management route to ldap server. First check the availavble routes,

    tmsh list sys management-route
    

    If you don't have route to LDAP, you have to add it, use the next expression:

    tmsh create /sys management-route  network / gateway 
    

    The BIG-IP system uses management routes to forward traffic through the management interface. For traffic sourced from the management address, the system prefers management routes over TMM routes and uses the most specific matching management route. If no management route is defined or matched, the system uses the most specific matching TMM route. If only a default gateway is defined as a management route, the system will prefer the TMM default gateway.
