Nextcloud Integrate with Zimbra or ldap freeradius

Hi guys

I am new to Nextcloud, successfully installed, it works fine. well at my place there is a mail client (zimbra) which is integrated with Ldap freeradius installed by my former boss. now HOW do I configure Nextcloud to be integrated with Zimbra or ldap freeradius so that users on zimbra or ldap freeradius can log into Nextcloud???
i have zero knowledge about Ldap freeradius and zimbra.

Nextcloud version 20.0.2
Operating system and version ubuntu 18.04
PHP version php7.2

nextcloud server 192.168.19.61/nextcloud
mail server (zimbra) 101.62.9.134
freeradius server 192.168.222.8

can you guys give me references or just tell me what i have to do. thanks in advance

You should be able to configure ldap user authentication with this.

Not really a solution:

But if you try to find a solution with other zimbra users, it would be great to share a tutorial…

owncloud and Nextcloud shared the same code some years ago, so some inspiration might be helpful from this side as well:

Thanks for reply All.

problem solved now i can login from my zimbra account.

just to /etc/freeradius/modules/ldap file i can see the configuration of host, cn, dc etc.
