This is a guide on how to setup LDAP authentication for users with Prosody. The LDAP server is OpenLDAP on FreeBSD -9- 10, but should work on any LDAP server. 

 h2. Prepare the Environment 

 * Install a couple dependencies: 
 <pre> 
 pkg install lua52-lualdap mercurial portmaster 
 </pre> 

 * Update the ports tree: 
 <pre> 
 portsnap fetch extract 
 </pre> 

 * Set the make.conf file to use Lua 5.1 at the default version to use while building: 
 <pre> 
 echo "DEFAULT_VERSIONS+= lua=5.1" >> /etc/make.conf 
 </pre> 

 * Install lualdap: 
 <pre> 
 portmaster net/lualdap 
 </pre> 

 h3. Install Prosody Modules 

 * Clone the prosody-module repo using mercurial: 
 <pre> 
 cd /usr/local/etc/prosody 
 hg clone https://hg.prosody.im/prosody-modules/ prosody-modules 
 </pre> 

 * Edit the prosody config: 
 <pre> 
 vi /usr/local/etc/prosody/prosody.cfg.lua 
 </pre> 
 #* And add the prosody-modules path to the plugins definition: 
 <pre> 
 plugin_paths = { "/usr/local/lib/prosody/modules", "/usr/local/etc/prosody/prosody-modules" } 
 </pre> 

 * Restart prosody: 
 <pre> 
 service prosody restart 
 </pre> 

 h2. Populate the LDAP Server 

 * Create the People Organizational Unit ldif file: 
 <pre> 
 vi ~/people-ou.ldif 
 </pre> 
 #* And add the following: 
 <pre> 
 dn: ou=People,dc=example,dc=com 
 objectclass: organizationalUnit 
 ou: People 
 </pre> 

 * Import the People OU file into the server: 
 <pre> 
 ldapadd -D "cn=Manager,dc=example,dc=com" -W -f ~/people-ou.ldif 
 </pre> 

 * Create the bob user ldif file: 
 <pre> 
 vi ~/bob.ldif 
 </pre> 
 #* And add the following: 
 <pre> 
 dn: cn=Bob Guy,ou=People,dc=example,dc=com 
 cn: Bob Guy 
 givenname: Bob 
 initials: BG 
 mail: bob@example.com 
 objectclass: inetOrgPerson 
 objectclass: organizationalPerson 
 objectclass: person 
 sn: Guy 
 uid: bob 
 userpassword: {MD5}X03MO1qnZdYdgyfeuILPmQ== 
 </pre> 
 #* *NOTE*: The password for bob is *password*. 

 h2. Setup LDAP Authentication 

 * Edit the ldap client config: 
 <pre> 
 vi /usr/local/etc/openldap/ldap.conf 
 </pre> 
 #* And adjust the following values: 
 <pre> 
 BASE     dc=example,dc=com 
 URI      ldap://ldap.example.com 
 </pre> 

 * Edit the prosody config: 
 <pre> 
 vi /usr/local/etc/prosody/prosody.cfg.lua 
 </pre> 
 #* And add the following values to the VirtualHost block: 
 <pre> 
 VirtualHost "example.com" 
	 enabled = true 

	 authentication = "ldap" 
	 ldap_base = "ou=People,dc=example,dc=com" 
	 ldap_server = "ldap.example.com" 
	 ldap_rootdn = "cn=Manager,dc=example,dc=com" 
	 ldap_password = "SuperSecretPassword" 
	 ldap_filter: (mail=%U@example.com) 


	 

	 ssl = { 
		 key = "/usr/local/etc/ssl/prosody.example.com.key"; 
		 certificate = "/usr/local/etc/ssl/prosody.example.com.crt"; 
	 } 
 </pre>
