I found a problem - when i wanted to change user password and use polish characters "łóóó" or something like this i receive "internal server error"

Currently it's not allowed and not a good idea to use non-ascii characters as password.
I will try to fix this. Thanks for your report.

I can't login using both accounts.

Error: Username or password is incorrect.

Fixed. Someone deleted testing accounts.

Error: Username or password is incorrect.

We're so sorry that iRedAdmin full-featured edition is delayed for more than two weeks, but it's ready to release iRedAdmin-1.0 now.

We will continue testing for about one week, hope to fix bugs and make it stable enough. but we need your help to test it, so that you can get a perfect version.

Demo is available:

- URL: http://demo.iredmail.org/iredadmin-ent/
- Username: postmaster@example.com (global admin), postmaster@test.com (normal admin)
- Password: iredmail

Note: It's not allowed to modify preferences of these two accounts, if you want to test to change admin preference, please create a new admin account and then login with the new one.
