Install the server as usual following the tutorial for Centos 7.2, Apache When instal ISPConfig3 Code: Admin password [admin]: 6pZZZZZZZSd Re-enter admin password []: 6pZZZZZZZSd When finished, go to URL, and "Username or Password wrong." Well. Usually copy & paste all password for a machine and after save on my system. Never type passwords. Well, I go to change manually Go to mysql Code: MariaDB [(none)]> use dbispconfig; UPDATE sys_user SET passwort = md5('NEWPASSWORD') WHERE username = 'admin'; MariaDB [dbispconfig]>quit; Got to ISPConfig interface and COPY & PASTE password, and not work. On last test, NEWPASSWORD has not any extended character. Only letters and Numbers. Also, verifiy that user 'ispconfig' on /usr/local/ispconfig/interface/lib/config.inc.php can connect to mysql database 'dbispconfig' [SOLVED] After see log tail -f /var/log/ispconfig/auth.log and on this logs show Sucessful logins, with original password, Suspect Dashlane, an extension of Chrome for password storage. And indeed it was the cause.
This prompt does not look familiar to me, are you by chance using the installation script which automates everything?
