ISE Ad join with ldap Secure

[Philip91]

Hello guys,

i use ISE with normal AD join. Right now Ad is running ldap. Will the communication between AD and ISE also work if i switch over to only allow ldap secure from AD site ?

Is there a way to configue it ?

I saw that when i configured lagacy ldap it is possible to enable or disable.

Thanks for your help

Hi,

You will need to change the port under connection settings to your LDAP ssl port and enable "Secure Authentications" with a trusted root ca between the two devices.

Hello Jason,

you are speaking about legacy ldap connection right ?

But i mean when i use "AD Join" and switch that to ldap secure. Then there is no option to configure ldap secure. Do you have any idea ?

Hi,

This is correct. I misunderstood your question. This should not have an effect as you are not connected via LDAP.

Hi,

what use the AD join instead of ldap ?

Watching the communication matrix shows that it uses ldap:

Protocol	Port (remote-local)	Target	Authenticated	Notes
DNS (TCP/UDP)	Random number greater than or equal to 49152	DNS Servers/AD Domain Controllers	No	—
MSRPC	445	Domain Controllers	Yes	—
Kerberos (TCP/UDP)	88	Domain Controllers	Yes (Kerberos)	MS AD/KDC
LDAP (TCP/UDP)	389	Domain Controllers	Yes	—
LDAP (GC)	3268	Global Catalog Servers	Yes	—
NTP	123	NTP Servers/Domain Controllers	No	—
IPC	80	Other ISE Nodes in the Deployment	Yes (Using RBAC credentials)	—

Hi Philip,

I will need to do this in a lab environment to test, which I suggest you do to. As far as I am aware you should be good with kerberos and rpc.
