I installed Icinga Web2 about this documentation: https://icinga.com/docs/icingaweb2/latest/doc/02-Installation/
Then I arrive the WebWizard without any issues. Even in the wizard all messages are green or blue. No problems are visible. But at the end I get an error message:
Unable to create user group “Administrators”. An error occured:
ERROR: Zend_Db_Adapter_Exception in /usr/share/icingaweb2/library/vendor/Zend/Db/Adapter/Pdo/Abstract.php:145 with message: SQLSTATE  FATAL: Ident authentication failed for user “icingaweb2”
Where I have to look for the error? I assume that the group Adminstrators should be a DB user group no linux group. If I try to connect to the DB as DB user icingaweb2 this is possible without problem. But I do not found a DB group Administrators (OK, the error msg. say that it was unable to create …)
I have add the DB rights to create roles and databases to the DB user icingaweb2, but this does not resolve the issue.
