Thank you.

Yes, the credentials are stored in AD.

I saw this documentation,
http://ltb-project.org/wiki/documentation/general/sasl_delegation

Helped me very much, but I think there are some wrong in my
saslauth.conf,
because when I put the AD server and ldap_filter = (sAMAccountName=%u is
Ok Success SASL, " but when I put my localhost like this:

ldap_servers: ldaps://127.0.0.1        #or ldap://localhost
#ldap_servers: ldaps://1.1.2.1
ldap_version: 3
ldap_auth_method: bind
ldap_search_base: cn=users,dc=foobar,dc=br
#ldap_filter: (sAMAccountname=%u)
#ldap_filter: (userPrincipalName=%u)
ldap_filter: uid=%u
ldap_bind_dn: cn=vmail,cn=users,dc=foobar,dc=br     #or
cn=admin,dc=foobar
ldap_password: abc@123
ldap_deref: never
ldap_restart: yes
ldap_scope: sub
ldap_use_sasl: no
ldap_start_tls: no
ldap_timeout: 10


testsaslauthd -u usertst -p password

NO "authentication failed"

See the log:

What can I do to fix this?


The log says that the entry is not found (nentries=0) either because
it does not exist, either because you can't read it (ACL).

But what are you using localhost behind your SASL pass trough? Seems
like you are doing a loop on your LDAP server.


Clément.


That is a problem, because don´t found the base but when I´m using
ldapsearch my search is acepted, very strange.

how this example:
ldapsearch -x -H ldaps://localhost -b dc=foobar,dc=com -D
cn=usertst,cn=users,dc=foobar,dc=com -w password

I see all objects in database, when I do this command.

If you had another idea please tell me, I just was seeing that link in the
ltb-project.org. where tell me to use in localhost SASL.


Seems you don't really understand how it works. OpenLDAP talks to
saslauthd on localhost, then saslauthd talks to AD. So don't configure
localhost in saslauthd, just set your AD settings in saslauthd.conf.

Clément.
All right, thanks for you help. but I´d tried this way before and too the users weren´t authenticated, the passwords weren´t accepted. 
For this I was tried another way.

But I can try, this way again if works I tell you.
