[Bug?] Sophos UTM forgets Bind DN password

Question

Hello. I have the strangest problem with our UTM (9.408-4): it does not save the password to bind to LDAP. If I enter the right password and test, everything is fine; but if I save and come back, I get the message "Error: Server exists and accepts connections, but bind to ldap://1.2.3.4:389 failed with this BindDN and password." 
 I can reenter the password and it will work again, but not after saving. As I have about 20 server entries, this is very annoying whenever I need to test VPN authentication. Quid? 
 
 Edit: This does not happen on my older Sophos UTMs (9.407-3), only on those updated to 9.408-4, so I am assuming this is a bug in the latest build.

Hi All, 
 The issue is fixed in the next firmware release. The JIRA ID for this bug is NUTM-5888. 
 Thanks

I found the latest update did fix this problem for me, but I had to completely delete the existing AD server first from: 
 Definitions & Users > Authentication Services > Servers tab 
 Then once I re-added the server all was well. 
 Let me know if this helps you.

Hello Bob, 
 Actually it always worked, in case your test connectivity is getting failed with CN=A,DC=B and DC=C you can go to the Windows power shell on the domain controller and run the command as C:\Users\Administrator> dsquery user 
 It will show you correct bind DN for each user and you can simply copy and paste the Bind DN into UTM for the required user and it works fine. 
 However you can also go with second approach as abc@xyz.local
