FTD External Authentication Bugged???

[WillDudeGuy]

Hi Community,

I'm have an issue getting external authentication working on my FMC managed FTDs(firepower 2100s). I have configured the remote authentication server under in the FMC settings and then navigated over to platform settings to enable it on the FTD. I deployed the config to the FTD but it doesn't actually make any changes to the FTD, i can tell this because i login to the FTD directly and can see that none of the LDAP settings are populated, and that the "set authentication default" command is still set to local rather then LDAP.

Anyone had any success with this?

This for admin or for RA VPN?

For admin

Can I see

Devics>Platfrom Settings>External Authentication

Also, watched the deployment of the firepower after i enabled the ldap in platform settings and wasn't able to see the creation of the server.

I would expect to see the following but i dont:

First we talk about admin FTD not FMC 

The config you share 

1- you enable external 

2- you need to select ssh and http when you add external authentication 

3-you use ssl with ldap' this can be issue if ftd dont have CA and identity cert. Then it can not connect to ladp using ssl

Do above and try access using ssh to ftd

??? whilst i appreciate you trying to help me out, posting configuration guides do nothing to help resolve the issue.

If you have followed the steps right, then I suggest open a TAC case mate.
