Forms Authentication...again

[AndreyZ]

I've worked farm with Project Web Access and configured froms based
authentication. Also i've about 20 users which use forms-based auth to login
to the PWA.
Now i want to change their passwords:
1. i've created update.xml file like this
<?xml version="1.0"?>
<Users xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://schemas.microsoft.com/Project/Users.xsd">

<UpdateUser>

<DisplayName>First Last</DisplayName>

<EmailAddr>[email protected]</EmailAddr>

<LogonName>user</LogonName>

<Password>Qwedkjlk234!23</Password>

<Guid>96f7b1bd-5a3d-469d-9b60-d9d4f473a80d</Guid>

<PasswordQuestion>question</PasswordQuestion>

<PasswordAnswer>answer</PasswordAnswer>

</UpdateUser>

</Users>

2. run
PjFormsAuthUpgrade -log forms.log -url http://mysite/pwa -usersfile update.xml

in log i've got
Reading users from users file C:\Program Files\Microsoft Office
Servers\12.0\Bin\update.xml.
User users read from users file.

User user already exists information not updated.
