Citrix receiver and XenApp


Citrix receiver Single Sign On to Citrix XenApp fails and users are prompted for a password when SecureLogin is installed
Customer expects to use Citrix SSO to pass credentials to Citrix XenApp.  This does not work when SecureLogin is installed.
SecureLogin breaks Citrix's own pass-through authentication.

Problem does not occur if Citrix Receiver is installed before SecureLogin is installed. 


Edit the network provider list and move the Citrix provider (PnSson) ahead of the SecureLogin network provider (slADCredMan)

Problem is specific to the sequence of installation and the resulting order of Network providers. This problem occurs when SecureLogin is installed before the Citrix receiver is installed.  SecureLogin is placed ahead of Citrix in the network provider list.

1. When Citrix receiver is installed (with include SSO option) after NSL installation, the following Network provider order is displayed: 
- "SecureLogin SSO Credential Manager" 1st and 
- "Citrix Single Sign-on" next.
Due to which, SSONSVR.EXE (citrix SSO module) failed to load.

2. When SecureLogin is installed after Citrix receiver the Network provider order displayed 
- "Citrix Single Sign-on" 1st and 
- "SecureLogin SSO Credential Manager" next, 
SSONSVR.EXE loaded without problem.
