Error in connection Windows - SAP PI

Dear,

Please, i'm trying a sap connection with an SFTP server and a folder in windows server. But that our SAP environment is within a Unix (AIX) server that does not access Windows shares (CIFS protocol) natively.

SAP PI in version 7.31 has a feature to access Windows shares from a Unix server or we will have to seek an alternative in the AIX operating system to access the share?

Thanks.
