[Jenkins-infra] Ldap Maintenance: 2018/04/28 - 1PM UTC

[Olblak]

Hello,

I'll move the Ldap server on Azure on Saturday 28th of April at 1PM UTC.
During the migration, new accounts creation will be disabled 
and you may face authentication issues on following services:
* Confluence - wiki.jenkins.io
* Jira - issues.jenkins.io
* Accountapp - accounts.jenkins.io
* Artifactory - repo.jenkins.io
* Jenkins - ci.jenkins.io

You can follow the state of the migration either on Jira (INFRA-1584) or irc (#jenkins-infra).

I'll send a message here when the migration is over.

Cheers
