How to generate an XOAUTH parameter using OAuth2.0 for use with Gmail IMAP protocol?

I have a user authorized to access their gmail through imap using OAuth2.0. I have the OAuth2.0 access token (and refresh token). But I am having trouble figuring out how to map that into an XOAUTH parameter. All the documentation for generating the XOAUTH parameter are written assuming OAuth1.0.

I can follow the sample code make this work with OAuth1.0. But my server is using OAuth2.0 for other things and I want to use the same code.

Security & Authentication: SSL vs SASL

My understanding is that SSL combines an encryption algorithm (like AES, DES, etc.) with a key exchange method (like Diffier-Hellman) to provide secure encryption and identification services between two endpoints on an un-secure network (like the Internet).

My understanding is that SASL is an MD5/Kerberos protocol that pretty much does the same thing.

So my question: what are the pros/cons to choosing both and what scenarios make either more preferable? Basically, I'm looking for some guidelines to follow when choosing SSL or to go with SASL instead. Thanks in advance!

Influence of KRC and SASL on Haskell?

While learning Haskell I took a side road (so to speak) in researching the Kent Recursive Calculator and SASL functional languages. I was immediately struck by the similarities between them and Haskell and since they predate it I wonder if/how they provided influence.

Any information regarding the influence (or lack thereof) of KRC and SASL on Haskell would be much appreciated.

Running the report browser (rb) for SASL error reports whilst in a remote shell

Folks we are now delploying a lot of Erlang instances and we are seeing bugs been thrown and would like to examine them...

Normally we connect to the running instance with a remote shell and get access to an Erlang console that way, but this doesn't work for rb or error messages...

How do I get remote access to my SASL error messages without dropping the server, starting it non-detached and looking at the shell?

Mac OS X 10.10 Yosemite Postfix SASL authentication failed

I followed the step described in the link below to setup my mac to send out email. http://www.anujgakhar.com/2011/12/09/using-macosx-lion-command-line-mail-with-gmail-as-smtp/

It was working fine on my Mac OS X 10.9. But after I upgraded to OS X 10.10. The mail.log showed the following error. What is the problem?

Secure this invaluable documentation on using C/C++ with GSSAPI and SASL

I have been working on using GSSAPI in c/c++ applications, for some time now. Obviously I had to google and research a lot. One of the most interesting documentation I discovered was on Sun's old web-site. After Oracle took over Sun, the old web-site is gone, and but somehow this information exists. http://docs.oracle.com/cd/E19253-01/816-4863/index.html Alarmingly, I couldn't find any link to the above url in Oracle's documentation. The content also included a couple of PDF files, which I luckily have preserved on my laptop.

The above URL also has an excellent guide on using SASL with c/c++.

The content referred to some tar file that contained sample source code. As per the current site content this file should be available at: http://www.sun.com/download/products.xml?id=41912db5 But unfortunately I can't locate them on the site now.

The content is an excellent starting point for a c/c++ programmer starting fresh on GSSAPI / Kerberos / PAM / SASL

Looking at Oracle's present site I strongly believe the content is presently left behind "accidentally" and will be soon gone.

Now here's my question to the fantastic hacks that visit stackoverflow:

1. Can you somehow replicate the content to some place, so that everybody can enjoy it's benefits?
2. Does anybody have a copy of the tar-ball that I am referring to? and would you be willing to share it?
3. Where must I upload these PDFs so that everybody can easily benefit?

I think the content is truly invaluable, and I can't think of any other web-source for such painstakingly clear information on using GSSAPI with C/C++. If you can do something about this, please do it now, because I think the above URL will be soon gone too.

My sincere thanks in advance, and I promise you many others will thank you too.

Edit: A bit of hunting around on Oracle's site and I discovered the link to one of the PDF's, but has been given a new name: Oracle Solaris Security for Developers Surely a gem of a reference if you are beginning to use GSSAPI / SASL with c++

SASL LDAP authentication failure

Trying to use SASL AND LDAP to authenticate user in RedHat Linux. So far I've setup the saslauthd service and its up and running. My /etc/saslauthd.conf looks like follows:

ldap_servers: ldaps://test.ldap.server:1234
ldap_use_sasl: yes
ldap_mech: DIGEST-MD5
ldap_auth_method: fastbind
ldap_search_base: Ou=PeopleAuthSrch,DC=abc,DC=com

My /etc/sasl2/smtpd.conf looks like the following:

pwcheck_method: saslauthd
mech_list: plain login

Now when I try to test the authentication with following command:

testsaslauthd -u username -p password -f /var/run/saslauthd/mux

I get 0: NO "authentication failed"

and when i look at the logs it says:

Retrying authentication
do_auth   :auth failure: [user:myuser]  [service=imap] [realm=] [mech=ldap] [reason=unknown]

What am i missing here? thanks in advance!!

UPDATE:

installed OpenLdap to do a search with the following command:

ldapsearch -x -h ldaps://my.ldap.server:port -d8

for ldapsearch command to work i modified /etc/openldap/ldap.conf file as follows:

tls_reqcert allow
TLS_CACERTDIR /home/myuser/cacertss
LDAPTLS_CACERT /home/myuser/cacertss

It returns all the entries but i still cant authenticate using

testsaslauthd -u username -p password -f /var/run/saslauthd/mux

what do i need to do here to get this authenticated?

ldap_sasl_bind_s(GSSAPI) - What should be provided in the credentials BERVAL structure

I'm trying to use the ldap_sasl_bind_s method from the Microsoft LDAP C SDK, with GSSAPI as the authentication mechanism. ldap_sasl_bind_s expects the credentials as a BERVAL structure, which is opaque.

Given a username (or a DN) and a password, how do I get to the BERVAL structure that I'm supposed to pass to ldap_sasl_bind_s?

The examples I've found so far

• are from other LDAP C SDKs - not the one from Microsoft
• use ldap_sasl_bind_s when SIMPLE authentication is desired - but I need to use GSSAPI
• use ldap_sasl_interactive_bind_s when other SASL authentication mechanisms are desired. However, there is no ldap_sasl_interactive_bind_s in the Microsoft SDK.

As a side note, the goal is to be able to bind over SASL to a variety of LDAP servers; for now: ActiveDirectory and OpenLDAP.

Any pointers will be greatly appreciated.

SMTP and OAuth 2

Does .NET support SMTP authentication via OAuth protocol? Basically, I would like to be able to send emails on users' behalves using OAuth access tokens. However, I couldn't find a support for this in the .NET framework.

Google provides some samples for this in other environments but not .NET.

HiveServer2: Thrift SASL related exception when using custom PasswdAuthenticationProvider

I've created a custom implementation of the PasswdAuthenticationProvider interface, based on OAuth2. I think the code is irrelevant for the problem I'm experiencing, nevertheless, it can be found here.

I've configured hive-site.xml with the following properties:

<property>
   <name>hive.server2.authentication</name>
   <value>CUSTOM</value>
</property>
<property>
   <name>hive.server2.custom.authentication.class</name>
   <value>com.telefonica.iot.cosmos.hive.authprovider.OAuth2AuthenticationProviderImpl</value>
</property>

Then I've restarted the Hive service and I've connected a JDBC based remote client with success. This is an example of a successful run found in /var/log/hive/hiveserver2.log:

Why? I've seen in several other questions this occurs when using the default value of hive.server2.authentication, i.e. SASL, and the client is not doing the handshake. But in my case, the value of such a property is CUSTOM. I cannot understand it, and any help would be really appreciated.

EDIT 1

I've found there are periodical requests to the HiveServer2... from the HiveServer2 itself! These are the requests that are resulting in Thrift SASL errors:

Any idea?

EDIT 2

More research about the connections sent from HiveServer2 to HiveServer2. Data packets always sent 5 bytes, the following ones (hexadecimal): 22 41 30 30 31

Any idea about these connections?

SMTP with CRAM-MD5 in Java

I need to send email through an (external) SMTP server from Java however this server will only accept CRAM-MD5 authentication, which is not supported by JavaMail.

What would be a good way to get these emails to send? (It must be in Java.)

Is libsasl2 broken on OSX Yosemite? Missing sasl_client_done

I've been having some trouble with the installed version of libsasl2 (Cyrus SASL).

In particular, it seems that the local headers and sasl_version report version 2.1.26, but no symbol is provided for the global function sasl_client_done.

I'm pretty sure I'm supposed to have that symbol because:

• It's there in the provided sasl/sasl.h header
• The cyrsus sasl NEWS file lists "Implemented sasl_client_done()/sasl_server_done()" as a 2.1.24 feature
• It's there everywhere that provides 2.1.26 outside of Yosemite

For a reproduction:

• note that the sample below prints
  • "impl: 'Cyrus SASL', version: 33619994, major: 2, minor: 1, step: 26"
• the sample compiles and executes on a linux install with the same library version after uncommenting the code

the uncommented code produces a link error on yosemite

And the code in question:

#include <stdio.h>
#include <stdint.h>

int main(int argc, char ** argv) {
    const char *impl;
    int version;
    uint32_t buf;
    uint16_t major;
    uint8_t minor;
    uint8_t step;

    sasl_version(&impl, &version);

    buf = version;

    major = buf >> 24;
    minor = (buf << 8) >> 24;
    step = (buf << 24) >> 24;

    printf("impl: '%s', version: %d, major: %d, minor: %d, step: %d\n", impl, version, major, minor, step);

    /*
    {
        int (* scd)(void);

        scd = &sasl_client_done;

        printf("sasl_client_done: %p\n", scd);
    }
    */

    return 0;
}

I'm thinking that something's screwy with the way cyrus sasl got packaged for Yosemite (using a symbol list from Mavericks perhaps?).

Erlang: What are strategies for dealing with huge SASL crash reports?

When my app crashes, I get a crash report that takes 5 minutes to scroll by. What's the best way to handle this?

SASL library for .net

I am searching for a sasl library for .net.

So far I could only find: Sasl.Net but it looks dead and only implements plain and digest-md5.

Can anyone suggest a good library? Preferably an open-source implementation.
