Password expired for Viadmin, no AD account linked and password can not be changed.

What version are you using?

How did you try to set up the new password?

The error looks like the password validation script ADS_PwdValidate was triggered but this shouldn't be the case if you do not have an AD account assigned. Unless you are using the same script in a different or custom password policy.

i installed the newest version 9.1 , im not using any script when i see the password requirements is also says i need an AD account linked for it to be able to reset the password.

How did you try to reset the password?

it forces me to reset when im trying to login to the launchpad, when i type in the username and password it says the password is outdated and it need to be reset.
Then a new screen comes up where i can change the password but it doesn't go true due to the account not being linked with an AD account.

The message does not mean you need a linked user account but points to the fact that an AD user password is checked by the script ADS_PWDValidate but the base object for the password check is no AD user account (in your case DialogUser). It shouldn't occur in your case. Please contact support to help you out.

Problem solved. I changed the password via SQL with the corresponding hash value. Now the question is: Can we manually generate the hash value using a tool?

There is no way as far as I know. But to prevent the expiry of DialogUser password you could set the DialogUser.PasswordNeverExpires flag as described in the documentation.
