SAP Connection with SNC Username and Password

Hi, 

We are using one idenitty Manager 9.1 and we are having an issue with connecting SAP in SNC Connection. We can connect to the SAP System without SNC without problems. 

We are using the SAPCrypto.dll library as SNC Client API. 

We have doubts about how to configure the SNC Hostname a SNC Name. We are setting the SNC Hostname with a string like p:CN=SAPXXXSNC, OU=Server XXX, O=Customer XXX, C=XX (given by the customer)

We are having an error message when tryng to enstablilsh connection with SAP Server 

LOCATION CPIC (TCP/IP) with Unicode
ERROR GSS-API(maj): No credentials were supplied
Unable to establish the security context
target="p:CN=SAPXXXSNC, OU=Server XXX, O=Customer XXX, C=XX"

Does anyone know how to configure the SNC Connection Data and if there are further requirements for the correct configuration? 

If anyone has ever configured a connection in SNC without SSO please help. 

Thank You ,

Enrico.
