Sonicwall NTLM authentication not working with Chrome

I have realised it is because the Sonicwall is using a Self Signed certificate.

IE11 is promting to continue and trust the self signed certificate. Chome is not prompting and jsut looping back to the first webpage.

Can I select one of the certificates in the sonicwall > certificates interface.

Can I genreate a .csr within the Sonicwall and purchase a signed certificate to use?

assign the SonicWALL a proper FQDN, set this on system?adminsitration.
Then provide a proper SSL cert.

then on User>settings there's a redirect to option, set this to configured DNS name :)

you can slect the cert o use on system?administration

you can create a csr from system > certificates.

That's great, thanks jspoor.

I created a .csr on the sonicwall. Have obtained a .crt certificate from a CA but when I click import it fails and the status remains 'Pending request' in the Sonicwall > certificates page?

Any ideas where I've gone wrong?

did you use the import button behind the csr ? could be the pen icon, been a while since I did that
don't use the import one below the certs

I've tried both now... getting desperate..!

The cert is SHA1

if you created a csr, then submit that to a ca, then behind the csr in the sonic is a server like icon with a green arrow. youuse that to import the .crt file.

if this keeps failing, you might want to import the CA servers intermediate CA certificates first.

I have imported the SSL cer using 'pending request' button successfully.

I have installed SHA256 Intermediate certificate from the CA. I have also imported a SHA1 intermediate certificate (as the Sonicwall OS is 5.8.1.11)

The SSL certificate is showing Validated 'NO'.

I'm hoping a reboot  at the end of the day would fix this?

validated NO, means you are missing an intermediate CA certificate

But I have installed 3 Globalsign intermediate certificates -

CA Root
Intermediate Domain Validation CA SHA256,
Intermediate Domain Validation CA SHA1 G2  
Intermediate Domain Validation CA SHA1

Apologies, the certificate is SHA256 and I just read Sonicwall 5.8.1.1 cannot use SHA256.

I upgraded the sonicwall to OS5.9 and it also upgraded the sonicpoints firmware and stopped the wireless.

Is there a way of upgrading the Sonicwall but leaving the sonicpoints on  their existing image?

I have upgraded the NSA240 to firmware 5.9 and the certificate is now working. Unfortunately, the Sonicpoints have stopped working. They advertise the SSID (that has always worked) but a client cannot join the wireless. Even using a WPA-PSK. The moment the Sonicwall is taken back to 5.8.1.11-62o the Sonicpoints re-image, reboot and start working again.

I tried to stop the Sonicpoints' firmware from upgrading by manually specifying the image path in Sonicwall > Sonicpoints to:

URL: software.sonicwall.com/applications/sonicpoint/sw_sp_eng_5.6.0.1_14.bin.sig
 
but still no client can join the SSID.

Many thanks for your help in solving the certificate issue.  I will award the points for the original question.

I forgot indeed, 5.8 doesn't support sha2 ....

SonicPoint support in 5.9 should be a lot better. not sure what broke in your case, but I am sure SonicWALL support can help you.

Just a note...

The wireless band had always been set to '802.11n only'. All the clients had 'n' compatible wNICs and could connect to '802.11n only' but after the firmware upgrade I had to set the sonicpoints to mixed mode '802.11b/g/n'.

Then all the clients rejoined!!

I have no idea why?

that sounds like a bug... could you please open a support case for this.
