Hi Francesco, 3.3.x comes with a very annoying bug regarding login: https://issues.apache.org/jira/browse/MARMOTTA-534
It's going to be fixed in 3.4.0 if we find time to finally cast the release. So, in the meantime, I guess you have three options (I summarize them to have it documented): 1) Changing user.admin.pwhash in your configuration file (requires restarting). 2) If you installation is not public and/or you don't care much about security, you can disable it. You have two ways of doing that: 2a) Changing *security.enabled = false* in your configuration file, as Xavier told you (requires restarting). 2b) Executing the following request from the same machine where Marmotta is running (allowed _only_ from localhost with the default simple profile): curl -X POST -H "Content-Type: application/json" -d '["false"]' http://localhost:8080/marmotta/config/data/security.enabled 3) Migrate to 3.4.0-SNAPSHOT, which currently can be considered a release candidate (the release is just blocked by a bug in the installer). Actually I'd recommend this last option for any new installation. I hope that helps. Apologize for all inconveniences.
