Client Authentication

Eduardo Paludo

Hello people,

I need some help, I updated a Sophos XG to SFOS firmware 17.5.12 MR-12, after the update, several authentication clients stopped working, using a linux client as an example, I ran the command:

openssl s_client -connect 1.2.3.4:9922 -tls1_2 -state -debug

The return is the error below:

ssl_connect error in sslv2 / v3 write server hello

Can someone help me solve it?

Thanks,

Best Regards.

    Hello Eduardo,

    Thank you for contacting the Sophos Community!

    Could you please elaborate a bit more on the issue you are having?

    What type of authentication are you using?

    Regards,

    I am using the authentication client. Users are from Active Directory. I have several stations with windows and linux and none of them authenticate users. This started to happen after the update I mentioned.

    For example in linux, I downloaded the client for linux x64, extracted the files, changed the configuration file and ran the ./bin/caa but the user does not authenticate, the error that occurs is:

    Failed to connect SSL () error code 5

    When I try to perform a test using the command:

    openssl s_client -connect host: 9922 -tls1_2 -state -debug

    The return is the error below:

    ssl_connect error in sslv2/v3 write server hello

    If I try using port 433, the connection occurs normally, it seems to be a problem with port 9922.

    Authentication clients use port 9922, right?

     

    Thanks, 

    Cheers.
