Logs

The key for the plugin is com.atlassian.plugins.authentication.atlassian-authentication-plugin.

The $BITBUCKET_HOME/log/atlassian-bitbucket.log file will show that after the latest restart, the plugin is installed:

However, there is no log entry stating that the plugin has been enabled. Searching for the string "'com.atlassian.plugins.authentication.atlassian-authentication-plugin' is now ENABLED" would not show any matches. There are no errors or warnings in the logs.
