Why do we use MID server? Purpose of using MID Server?

What is the exact need of MID server except discovery?
Is there any need of MID server while integrating with any tool?

Here goes a complete list of options (from the wiki) of how the LDAP integration could be setup:

LDAP typically uses one of these types of communication channels:

A MID Server connection communicates over HTTP on port 80 by default. This communication channel does not require a certificate. The connection between the MID Server and the instance is over HTTPS (port 443). You can use the MID Server to import data over LDAP, but you cannot use the MID Server for LDAP authentication. Proceed to Define the LDAP Server.
A standard LDAP integration communicates over TCP on port 389 by default. This communication channel does not require a certificate. Proceed to Define the LDAP Server.
An SSL-encrypted LDAP integration (LDAPS) communicates over TCP on port 636 by default, This communication channel requires a certificate. Proceed to Upload the X.509 Certificate to obtain and upload the certificate.
A VPN connection communicates over an IPSEC tunnel. Purchase or create an IPSEC tunnel on your local network. Proceed to Define the LDAP Server.

A MID server initiates one connection to an LDAP server via port 398, then initiates an encrypted HTTPS connection to an instance via port 443 to push data to the instance. When using a MID server, the instance does not make the connection to the LDAP server. The MID server does.

The instance can also connect to the LDAP server directly, using LDAP or LDAPS, either over the internet or through a VPN tunnel.

For more information about VPNs, Mid Servers, and LDAP, see You Don't Need A VPN Part II on the ServiceNow Community.

I hope this helps.

Thanks,

LDAP integration requires mid server,

MID Server communications are initiated inside the enterprise's firewall and therefore do not require any special firewall rules or VPNs.

Hi,

The LDAP integration can leverage the MID server but you can also setup your LDAP integration without a MID Server. The MID Server is a good option to leverage whenever the LDAP Server is not reachable from outside the company's network where the AD resides.

Thanks,

So is this saying that if people are not connected to the corp network, either physically, or via vpn, then they cannot SSO into SN due to LDAP integration not being accessible from outside the network?
