The default encryption algorithm of htpasswd stores passwords in MD5 format. If you take a look at the file it prefixes the password with $apr1$. This format was not handled by the Check_MK GUI. If you set the prefix to $1$ it worked.
The GUI has been changed to be able to work with both formats. Passwords set with this command should now work out of the box:
htpasswd -m $OMD_ROOT/etc/htpasswd [username]
