The integration is free. ## Before you start You need an LDAP-compatible directory server reachable from the internet, and: * Its public **IP address or host name** and **port**. * The names of the attributes that hold each user's **full name** and **email**. Every user must have an email attribute — users without one can't sign in. * An admin user with at least **read** and **search** permissions over the users who'll sign in. ## Setting up LDAP 1. Go to **Settings → Integrations → LDAP** and turn on **Enable LDAP integration.** 2. Enter the **Server IP/host** and **Server Port**, and turn on **Use SSL to connect to server** if your server uses it. 3. Enter the **Bind expression** and **Search expression** your directory uses to find users, and the **Password** of the admin user. 4. Enter your **Full name attribute** and **Email attribute** names. 5. Choose whether to **Create new users in Nexudus if they don't exist.**, and save. LDAP settings With **Create new users** on, anyone with valid directory details can sign in, and gets a Nexudus contact account named after their directory name and email if they don't have one. With it off, only people whose Nexudus email matches their directory email can sign in. ## Related * [Single sign-on](/integrations/sso) — shared SSO options This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
