Hi,I'm using Apache 2.4.7 on Ubuntu 14.04 and I need to use the mode mod_auth_dbd with the AuthDBDUserRealmQuery. I have mysql installed and working. I followed the documentation, activated all the needed apache modules (hopefully), and configured the 000-default.conf file, under the VirtualHost field (I'll need this authentication in a reverse proxy mode). First, I tested the simple AuthDBDUserPWQuery directive, that works without problems.The issue occurs when I activate the AuthDBDUserRealmQuery directive, removing the AuthDBDUserPWQuery. The resulting VirtualHost file is<VirtualHost *:80>ServerAdmin webmaster@localhostDocumentRoot /var/www/htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combinedDBDriver mysqlDBDParams "host=localhost port=3306 user=my_user pass=my_password dbname=apacheauth"DBDMin 2DBDKeep 4DBDMax 10DBDExptime 300<Directory /var/www/html>AuthName "You Must Login"AuthType BasicAuthBasicProvider dbdRequire valid-userAuthDBDUserRealmQuery "SELECT ENCRYPT(password) FROM password WHERE username = %s AND realm = %s"</Directory></VirtualHost>When I try to access with user and password through basic authentication, what happens is that the error.log file of apache is reporting this error:[authn_dbd:error] [pid 40782:tid 140490237867776] [client some_ip:some_port] AH01654: No AuthDBDUserPWQuery has been specifiedI searched a lot on the Web, but I didn't find anything.Thank you,Best,EBPS: I already tried the query both with ENCRYPT and without it.
