To configure the DMZ connecting with Password Manager please follow the steps out lined below:
1) Install just the PMUser site on the DMZ server
2) Launch the PMUser site after installation from browser window or IIS
3) On the initialization screen provide the IP address and the port that will be accessing the backend service server
4) Make sure the Port and the encryption key that is used match what is listed on the PMAdmin site-> general settings-> reinitialization screen
Note: the certificate that is listed here is not an SSL certificate, it is simply the certificate used to encrypt the data between the DMZ and the backend service server. The most important thing is that what you enter in the DMZ initialization screen matches what is listed in the PMAdmin site.
