Siebel Issue: Could NOT access Administration-Server Configuration and Management in S80

When I access ‘Sitemap>Administration-Server Configuration’ and ‘Sitemap>Administration-Server Management’ with Siebel8.0 Mobile Web Client (Thick client), a ‘Siebel Web Session’ Error Message appears as follows:
The User ID or password that you entered is incorrect.
Please check the spelling and try again.
If you click OK button to close this dialog box, a new Login Screen will be showing. And default ‘Connect to’ text field is ‘Gateway’. You are NOT able to modify this value.
In addition, I’m sure that my inputs are correct. And I can access these two screens with same user ID and password with Siebel8.0 Web Client (thin client) successfully.

 

Solution:

Re-configure *.cfg file as below,

[GatewayDataSrc]
ConnectString = CHANGE_ME
PrimaryEnterprise = CHANGE_ME
DLL = sscda10.dll
Hidden = TRUE

For example,

[GatewayDataSrc]
ConnectString            = vm09
PrimaryEnterprise        = SIA80
DLL                      = sscda10.dll
Hidden                   = TRUE
