Product Line

Security Expert


  • Security Expert Server
  • Security Expert Web Client
  • Security Expert SOAP Service


There are no available client connections.

When the SOAP service attempts to connect to Security Expert it performs an Operator login to the Data Service, pulls/pushes the information it needs, and then closes the connection. This means that if you are using all your concurrent operator logins at any given time with Thick Client connections, SOAP will not be allowed to log in, and any services requiring the SOAP connection will also not work.

SOAP will only use one concurrent connection even if it has multiple services connected to it, so you would not need multiple connection licenses if you had Web Client, Data Sync, and EWS, for example.


If all the connections are being consumed with Thick Client logins, then reduce the number of people that are logged in at any given time or purchase an additional concurrent client license so there is one free for SOAP to use.
