Problems with AD synchronization after installing Sophos Web Appliance update v4.3.3

Hi,

I'm experiencing AD synchronization problems after installing Sophos Web Appliance update v.4.3.3. It seems to be a problem with SMBv2. LDAP settings test fails. Before installing this update, we never experienced such problems. Is there anybody that is experiencing similar problem? I would appreciate so much if somebody can share the solution to this problem.

Thank you.

I have a case open with Sophos regarding AD Sync issue and they have confirmed it's a known issue that will be fixed in next release 4.3.5.

For me, AD Sync flags up an error every day or two but eventually it finds it's feet again and sync works. At worst I have to set the "Auto-detect advanced settings" followed by "Verify Now" and it usually fixes it.

I hope the next release sorts this one out.

Version 4.3.5 Release Notes

This release includes the following updates and fixes.

Resolved Issues

Work Order	Description
NSWA-1284	Fixed an issue in which using an upstream proxy could cause error messages on managed endpoints.
NSWA-1383	Added support for the new Asia Pacific Sandstorm data center.
NSWA-1404	Increased compatibility and security of syslog.
NSWA-1516	Fixed a cache issue when editing the local site list, in which entries could be duplicated or not saved correctly.
NSWA-1520	Fixed an issue with memory management.
NSWA-1522	Fixed an issue in which LinkedIn would be blocked due to an invalid response.
NSWA-1525	Fixed an issue using special characters for FTP backups.
NSWA-1528	Fixed an issue where FTP backups could not recover after a failure.
NSWA-1534	Fixed an issue where AD could fail due to DNS lookup.
NSWA-1540	Fixed an issue that could cause updates to hang if there were network problems.

I'll start the WEB virtual appliance tonight to lurk it ... It has been shutdown for weeks now ... The list of correction is rather very shy. Secure connection to AD is not mentioned, so I presume it is not fixed.

That's good news! I'll keep an eye on my web appliance to see when it becomes available for install.

Still no trace of update appearing in the appliance. Not too surprising since we are told this update mostly connects Sandstrom's Asian users to Asian servers. Sophos most probably pushes updates there first.

I understand the 4.3.5 release is only available to select customers at the moment (probably to test it) but hopefully it'll be released to everyone soon.

M. Hill, out of my curiosity, what's in 4.3.5 that addresses a problem you currently experience ?

The Active Directory Synchronisation connection drops out every other day. I tried all the documented troubleshooting suggestions and eventually raised a support case with Sophos who confirmed the issue will be resolved in the next release (4.3.5).

I do not care that much since we are not using the Sophos' WEB gateway anymore. But by curiosity, I start the appliance once a week, or something like that. It shows I need to update Sophos' certificate, but besides that, I have no update showing up ...

Update: There's a 4.3.5.1 version released ... swa.sophos.com/.../ReleaseNotes_4.3.5.1.html

I fired up the WEB appliance this PM. Version 4.3.5.1 installed. I do not know how circumstantial that is, but connection to LDAP via 3268 port worked many times in a row. I will restart that appliance in the coming weeks to see if it has become reliable on that 3268 port.
