PasswordServer does not work anymore

You dont say whether you are using a Citrix broker or a MS broker.

Try dropping the second sign on server.  It is not clear if that parameter supports multiples

PasswordServer=10.235.10.51 AccountSelfService=yes Connect=RDP

This is the complete config and this was working all the time. Now after upgrade firmware the part of the passwordserver in case of expired password does not work anymore. The time before if a password expired and user try to login with old password an RDP session to one of the passwordserver etablish and on these machine they can change their domain password. We don´t use AccountSelfService on our Citrix farm.

You may want to reconsider posting your entire INI.  There are probably some things in there you dont want public.

Since you are using Citrix and Storefront I would suggest changing the device to use Storefront mode

         PnliteServer=http://hdx.hq.leschaco.org Storefront=yes

remove the passwordserver= line

Add passwordnotify to your Sessionconfig=ICA line

           SessionConfig=ICA PasswordExpireNotify=yes SessionReliability=yes

Make sure the storefront server is configured to allow password changes "At any time".    The device will leverage storefront to be told when to change password for a user, and a dialog box will appear and allow the user to change password, without having to establish a session against a user.

Thanks. I already change this and and I can also confirm that storefront server configured password changes to "At any time", but still does not work.

If user with expired password try to logon to Wyse Box, ThinOS open a popup-windows and confirm that password expired and ask to change to new one. But after set new password and confirm new password, nothing happens and ThinOS return to normal Logon Window again. Still can not logon with old or new password and we get into a loop.

Any other ways to implement password change servers? Until we upgrade to latest firmware it works fine with PasswordServers connection via RDP.

I am sorry to hear that.  I recommend you open a support ticket.
