Jira server fails to connect to LDAP server with UnknownHostException


アトラシアン コミュニティをご利用ください。



JIRA is unable to connect to the LDAP server.

atlassian-jira.log に次のエラーが返される。

Caused by: org.springframework.transaction.CannotCreateTransactionException: Could not create DirContext instance for transaction; nested exception is org.springframework.ldap.CommunicationException: ldap.atlassian.com; nested exception is javax.naming.CommunicationException: ldap.atlassian.com [Root exception is java.net.UnknownHostException: ldap.atlassian.com]


JIRA cannot resolve the connection to the LDAP server. This is commonly caused by an incorrectly configured DNS or hostname.


  1. Update the DNS records to include the appropriate server name & IP used in the LDAP configuration.
  2. If updating of the DNS server used is not possible, this can be achieved by manually adding the following entry, replacing the IP & server name as appropriate to the below file on the server hosting JIRA. 
    Linux: /etc/hosts
    Windows: C:\Windows\System32\drivers\etc\hosts

    <IP of server>    <host name of server>     ldap.atlassian.com

    You need to have local administrator rights on the machine hosting JIRA to make these changes.

  3. Alternatively, you can use the IP of the server in the LDAP configuration, as in Connecting to an LDAP Directory.

(info) We also have some additional steps for LDAP troubleshooting, please review these if you're still experiencing problems.
