I've been trying to find the right OAP command for changing the password for OpenVAS users.
It is possible to change it the Greenbone Security Assistent interface. But i can't find it for doing it through CLI.
-c, --command=<command> OAP command (e.g. add_user, remove_user, list_users)
OAP command does allow to add or remove user but i can't find the command to edit user settings.

I don't believe you can change the password via command line. However the following script does so by changing the password hash directly in the users file.
Create a file containing the script in the following link and execute it: http://lists.wald.intevation.org/pipermail/openvas-discuss/2013-January/004879.html
Works fine on CentOS 6.
