multiple user with multiple secured directories are not working as expected. user will be deleted/overwritten in htpasswd not added.
for reproducing try this:
1. add a secured directory for example: /var/www/virtual/domain.de/secured_dir1/
secure it for: user_a
--> user_a will be created in /var/www/virtual/domain.de/.htpasswd
2. add a second dir and secure it with different user:
/var/www/virtual/domain.de/secured_dir2/
secure it for: user_b
--> now user_b will not be _added_ - it just overwrites user_a in /var/www/domain.de/.htpasswd with user_b
--> in gui everything looks normal and as expected (2 dirs with 2 different users) - but only one user exists in real
