414 | SRA 6.0 Administrator’s Guide
Answer: Prior to 2.5 firmware: No, the appliance can only by managed using the X0’s IP
address. With 2.5 firmware and later, yes, you can manage on any of the interface IP
addresses.
45.
Can I allow only certain Active Directory users access to log into the SRA appliance?
Answer : Yes. On the Users > Local Groups page, edit a group belonging to the Active
Directory domain used for authentication and add one or more AD Groups under the AD
Groups tab.
46.
Does the HTTP(S) proxy support the full version of Outlook Web Access (OWA Premium)?
Answer : Yes.
47.
Why are my RDP sessions dropping frequently?
Answer: Try adjusting the session and connection timeouts on both the SRA appliance and
any appliance that sits between the endpoint client and the destination server. If the SRA
appliance is behind a firewall, adjust the TCP timeout upwards and enable fragmentation.
48.
Can I create my own services for bookmarks rather than the services provided in the
bookmarks section?
Answer : This is not supported in the current release of software but may be supported in
a future software release.
49.
Why can’t I see all the servers on my network with the File Shares component?
Answer : The CIFS browsing protocol is limited by the server's buffer size for browse lists.
These browse lists contain the names of the hosts in a workgroup or the shares exported
by a host. The buffer size depends on the server software. Windows personal firewall has
been known to cause some issues with file sharing even when it is stated to allow such
access. If possible, try disabling such software on either side and then test again.
50.
What port is the SRA appliance using for the Radius traffic?
Answer : It uses port 1812.
51.
Do the SRA appliances support the ability for the same user account to login
simultaneously?
Answer: Yes, this is supported on 1.5 and newer firmware releases. On the portal layout,
you can enable or disable ‘Enforce login uniqueness’ option. If this box is unchecked, users
can log in simultaneously with the same username and password.
52.
Does the SRA appliance support NT LAN Manager (NTLM) Authentication?
Answer : Yes, in SRA 5.0 and later releases, backend Web servers using NTLM or Windows
Integrated Authentication are supported. Single Sign-On with NTLM is also supported.
NTLM support is specific to Application Offloading and/or reverse-proxy bookmarks.
SRA 3.5 and earlier do not support NTLM authentication. As a work around, the
administrator can turn on basic or digest authentication. Basic authentication specifies the
username and password in clear text, but the security outside the intranet is not
compromised because the SRA uses HTTPS. However, the intranet is required to be
“trusted”. Digest authentication works better in this case, because the password is not sent
in clear text and only a MD5 checksum that incorporates the password is sent.
53.
I cannot connect to a web server when Windows Authentication is enabled. I get the
following error message when I try that: ‘It appears that the target web server is using an
unsupported HTTP(S) authentication scheme through the SRA, which currently supports
only basic and digest authentication schemes. Please contact the administrator for further
assistance.’ - why?
