Subject [jira] [Commented] (GUACAMOLE-205) libguac_common_ssh build fails with OpenSSL 1.1
Date Thu, 29 Jun 2017 01:03:00 GMT


Mark Goldey commented on GUACAMOLE-205:

Thanks, Michael.  I do see that now.  I was able to compile 0.9.13 from git and can confirm
that the errors have vanished.

Ironically, I'm back to where I started those many months ago, when I upgraded my Debian box
from Jessie to Stretch and 0.9.9 stopped authenticating despite having worked fine before
and no change in user-mapping.xml or any other configuration files.  I get this in catalina.out:

{code:none}20:55:12.899 [https-jsse-nio-8443-exec-3] WARN  o.a.g.r.auth.AuthenticationService
- Authentication attempt from for user "mark" failed.{code}

I tried using the 0.9.12 guacamole.war and it does the same thing.  Is there a specific .war
file to instead use with 0.9.13?  I couldn't find one.

Again, thanks for all your help.

>    Affects Versions: 0.9.11-incubating

>            Reporter: Mark Goldey
>            Assignee: Michael Jumper
>             Fix For: 0.9.13-incubating
> There are a number of changes in OpenSSL 1.1 which break compatibility with older versions
of the API, and which break the Guacamole build if OpenSSL 1.1 is present, particularly the
removal of threading callbacks (replaced with no-op macros) and the migration to opaque structures
with public accessor functions. The error below is due to the no-op macros, and fixing those
reveals further errors due to the new and required public accessor functions.
> A rough list is here:
> The Guacamole build will need to be updated to take these changes into account. The original
