Environment


Novell Access Management 3 SSLVPN Server

Situation

When I connect to an SSLVPN server, most of my protected applications work fine (telnet, FTP, Groupwise were all tested successfully). However some other applications fail such as Microsoft Outlook talking to an Exchange server using MAPI.

Resolution

Regarding Microsoft Outlook, if the client talks to a POP3, IMAP, or HTTP backend then you should be OK. If it is talking to Exchange normally then it uses MAPI (an RPC call) which does not go via the winsock layer and the SSLVPN redirector client does not intercept it. The SSLVPN client only intercepts TCP and UDP winsock calls made after the SSLVPN tunnel is brought it.

We cannot map NetWare drives or talk to Windows file shares due to a combination of

- processes started at bootup and
- NetBIOS is used rather than Winsock.
