  1. Install the plugin through the Update Center or download it into the SONARQUBE_HOME/extensions/plugins directory
  2. Restart the SonarQube server


  1. Make sure that at least one user with System administration role exists in SonarQube as well as in the external system
  2. Configure the LDAP plugin by editing the SONARQUBE_HOME/conf/ file (see below)

  3. Restart the SonarQube server and check the log file for:

    INFO org.sonar.INFO Security realm: LDAP

    INFO o.s.p.l.LdapContextFactory Test LDAP connection: OK

  4. Log into SonarQube

General Configuration

PropertyDescriptionDefault valueMandatoryExample

This property must be defined to ask the SonarQube server to use first the LDAP plugin when trying to authenticate a user.



LDAP (no other value can be used) optional property can be used to ask SonarQube to save the user password in the SonarQube DB. When this property is activated, a user can log into SonarQube even when the LDAP server is not available.falseNo 
sonar.authenticator.createUsersBy default, the SonarQube DB is automatically populated when a new SonarQube user logs into SonarQube. Setting this value to false, make it mandatory for a System administrator to first declare a user in the SonarQube DB before allowing this user to log into SonarQube.trueNo 
sonar.authenticator.updateUserAttributesIf set to 'true', at each login, user's attributes (name, email, etc.) are re-synchronized. If set to 'false', user's attributes are not re-synchronized except when creating the user for the first time (sonar.authenticator.createUsers=true).
Available since SonarQube 3.6.
ldap.urlURL of the LDAP server. Note that if you are using ldaps, then you should install server certificate into java truststore. Yes (Not mandatory in case of Auto-discovery)ldap://localhost:10389
ldap.bindDnBind DN is the username of an LDAP user to connect (or bind) with. Leave blank for anonymous access to the LDAP directory. Nocn=sonar,ou=users,o=mycompany
ldap.bindPasswordBind Password is the password of the user to connect with. Leave blank for anonymous access to the LDAP directory. Nosecret
ldap.authenticationPossible values: 'simple', 'CRAM-MD5', 'DIGEST-MD5', 'GSSAPI'. See description
ldap.contextFactoryClass(advanced option) Context factory 

User Mapping

PropertyDescriptionDefault valueMandatoryExample for Active Directory Server
ldap.user.baseDnDistinguished Name (DN) of the root node in LDAP from which to search for users. Yes (Not mandatory in case of Auto-discovery)cn=users,dc=example,dc=org
ldap.user.request(available since plugin version 1.2)
No Format
No Format
ldap.user.objectClassDeprecated in plugin version 1.2 and replaced by 'ldap.user.request'. Object class of LDAP users.inetOrgPersonNouser
ldap.user.loginAttributeDeprecated in plugin version 1.2 and replaced by 'ldap.user.request'. Attribute in LDAP holding the user’s login.uidNosAMAccountName
ldap.user.realNameAttributeAttribute in LDAP holding the user’s real name.cnNo 
ldap.user.emailAttributeAttribute in LDAP holding the user’s email.mailNo 

Group Mapping

The following properties should be defined to allow SonarQube to automatically synchronized the relationships between users and groups.

There are two limitations:

  • Groups must be static and not dynamic
  • The user entry must contain the attribute 'memberOf' with list of groups
PropertyDescriptionDefault valueMandatoryExample for Active Directory Server Name (DN) of the root node in LDAP from which to search for groups. 

Yes in version 1.1.1

No in version 1.2, if you want to disable synchronization of groups.

cn=groups,dc=example,dc=org since plugin version 1.2)
No Format
No Format
(&(objectClass=group)(member={dn})) in plugin version 1.2 and replaced by ''. Object class of LDAP groups.groupOfUniqueNamesNogroup in LDAP holding the group's id.cnNo in plugin version 1.2 and replaced by ''. Attribute in LDAP holding the group's member.uniqueMemberNomember

Example of LDAP Configuration

Code Block
# LDAP configuration


Advanced Configuration


Here is description of how auto-discovery works:

  1. Determine DNS Domain Name:
    • from "ldap.realm" property if set
    • from FQDN of machine, where SonarQube is installed (eg. if FQDN is "", then DNS Domain Name will be "")
  2. Determine URL of LDAP server:
    • from "ldap.url" property if set
    • from DNS server ( see known limitations ), here is example of SRV Record for domain "":

      No Format 72784   IN      SRV     0 5 389

      for this domain URL of LDAP server will be "ldap://"

  3. Determining BaseDN:
    • from "ldap.baseDn" property if set
    • from DNS Domain Name (eg. if DNS Domain Name is "", then BaseDN will be "dc=example,dc=org")

Authentication Methods

  • Simple
    Simple authentication is not recommended for production deployments not using the secure ldaps protocol as it sends a cleartext password over the network.
  • Anonymous
    Used when only needs read-only access to non-protected entries and attributes when binding to the LDAP server.
  • CRAM-MD5
    The Challenge-Response Authentication Method (CRAM) based on the HMAC-MD5 MAC algorithm (RFC 2195).
    This is an improvement on the CRAM-MD5 authentication method (RFC 2831).
    GSS-API is Generic Security Service API (RFC 2744). One of the most popular security services available for GSS-API is the Kerberos v5, used in Microsoft's Windows 2000 platform.
