admin/openstack credentials do not work to log into the openstack BUI. Could you please provide the correct credentials?
When you installed OpenStack you set the password. If you used the username and password from the lab, they should be admin with a password of openstack. Please check the log file /opt/stack/logs/stack.sh.log or the ~/devstack/.localrc.auto file which also has the username and password.
Thanks! It was my fault. In fact the passwd was configured in the local.conf file, the problem is that I created the file as local.cnf instead of local.conf, so the default passwd were not taken from the config file.
Thanks a lot for the answer!
