Tech:Ldap

Miraheze uses ldap as an authentication system for some of our infrastructure such as Grafana and Icingaweb2.

You can use  to modify a user, add a user or change the roles the user has. You can also use https://ldapwiki.miraheze.org to change your password.

You can find the ldap password in /etc/ldapvi.conf. All these steps have to be done using ldap141.miraheze.org.

Terminology:
 * cn = Common Name


 * sn = Surname


 * UID = username you'll login with


 * givenName = First Name

Add New User
1. Add the following to a file named user.ldif: dn: uid= ,ou=people,dc=miraheze,dc=org changetype: add objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson uid: givenName:  sn: cn:  userPassword:

The 'uid' attribute is equal to the username you are using. It is recommended to set the 'cn' attribute equal to the contents of 'uid'. 'givenName' is usually your first name, while 'sn' is your surname. You cannot directly put your password in this ldif file, instead you need to generate a hash through.

2. Run.
