Password error when Changing certificates with SSL Automation Tools

Hello,

When I try to change SSL Certicates with  SSL Automation Tools on the vCenter Server it faild when changing certificate for vCentere Single Sign-On.

Here is the ssl-environment.bat file :

rem Common parameters
set sso_admin_user=admin@System-Domain

Error :

.
[.] Found vCenter Single Sign-On Server installation in: C:\Program Files\VMware
\Infrastructure\SSOServer\
[.] Verifying master password.
[.] ERROR: The provided master password is incorrect.

[08.04.2013 - 14:12:45.31]: Last operation update the Single Sign-On SSL certifi
cate failed :

When I try to log into the vCenter with admin@System-Domain it works.

Where is the mistake?

Thanks.
