LDAP Examples

Here are some examples of the LDAP settings and their values. The examples will be based on these environments:

  • Host = ldap.domain.com
  • Group = CN=ROCKET_ACCESS,CN=Users,DC=domain,DC=com (Access Control Group)
  • Proxy User = rocket.service@domain.com or CN=rocket service,CN=Users,DC=domain,DC=com (DN or userPrincipalName)
  • Proxy User password = urpass (Proxy Users password)

{% hint style="warning" %} Replace the values above with your respective environment. {% endhint %}

Log on with a username

  • LDAP_Enable = True
  • LDAP_Dn = dc=domain,dc=com
  • LDAP_Url = ldap://ldapserver
  • LDAP_Port = 389
  • LDAP_Bind_Search =

{"filter": "(&(objectCategory=person)(objectclass=user)(memberOf=CN=ROCKET_ACCESS,CN=Users,DC=domain,DC=com)(sAMAccountName=#{username}))", "scope": "sub", "userDN": "rocket.service@domain.com", "password": "urpass"}

If you need to auth users from subgroups in LDAP use this filter:

LDAP_Bind_search = {"filter": "(&(objectCategory=person)(objectclass=user)(memberOf:1.2.840.113556.1.4.1941:=CN=ROCKET_ACCESS,CN=Users,DC=domain,DC=com)(sAMAccountName=#{username}))", "scope": "sub", "userDN": "rocket.service@domain.com", "password": "urpass"}

Log on with an email address

  • LDAP_Enable = True
  • LDAP_Dn = dc=domain,dc=com
  • LDAP_Url = ldap://ldapserver
  • LDAP_Port = 389
  • LDAP_Bind_Search =

{"filter": "(&(objectCategory=person)(objectclass=user)(memberOf=CN=ROCKET_ACCESS,CN=Users,DC=domain,DC=com)(mail=#{username}))", "scope": "sub", "userDN": "rocket.service@domain.com", "password": "urpass"}

Log on with either an email address or username

  • LDAP_Enable = True
  • LDAP_Dn = dc=domain,dc=com
  • LDAP_Url = ldap://ldapserver
  • LDAP_Port = 389
  • LDAP_Bind_Search =

{"filter": "(&(objectCategory=person)(objectclass=user)(memberOf=CN=ROCKET_ACCESS,CN=Users,DC=domain,DC=com)(|(mail=#{username})(sAMAccountName=#{username})))", "scope": "sub", "userDN": "rocket.service@domain.com", "password": "urpass"}

Log in

When you enable LDAP, the login form will log in users via LDAP instead the internal account system.

LDAPS - SSL Connection

Use stunnel to create a secure connection to the LDAP server. Create a new configuration file /etc/stunnel/ldaps.conf with the following content:

options = NO_SSLv2

[ldaps]
client = yes
accept = 389
connect = your_ldap_server.com:636

To enable Stunnel automatic startup, change the ENABLED variable in /etc/default/stunnel4 to 1:

# Change to one to enable stunnel automatic startup
ENABLED=1

Finally, on the Rocket.Chat server under /admin/LDAP set these values:

  • LDAP_Url = localhost
  • LDAP_Port = 389
