First post on StackExchange - please go easy :)
I have setup ODBC in Centos 6 in order to perform ms-sql queries from my Asterisk installation.
My Config files are:
/etc/odbc.ini
[asterisk-connector]
Description = MS SQL connection to 'asterisk' database
Driver = /usr/lib64/libtdsodbc.so
Setup = /usr/lib64/libtdsS.so
Servername = SQL2
Port = 1433
Username = MyUsername
Password = MyPassword
TDS_Version = 7.0
/etc/odbcinst.ini
[odbc-test]
Description = TDS connection
Driver = /usr/lib64/libtdsodbc.so
Setup = /usr/lib64/libtdsS.so
UsageCount = 1
FileUsage = 1
/etc/asterisk/res_odbc.conf
[asterisk-connector]
enabled => yes
dsn => asterisk-connector
username => MyUsername
password => MyPassword
pooling => no
limit =>
pre-connect => yes
I am able to connect via ISQL when I pass in the password and username:
[root#TestVM etc]# isql -v asterisk-connector MyUsername MyPassword
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL>
..but I should be able to connect without the username / password. All that returns is:
[root#TestVM etc]# isql -v asterisk-connector
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[01000][unixODBC][FreeTDS][SQL Server]Adaptive Server connection failed
[ISQL]ERROR: Could not SQLConnect
It is as if ISQL cannot read the username and password from the config files.
I need to be able to perform MS-SQL lookups from within the Asterisk dialplan, but for that to happen I must be able to call ISQL with just the data source name and can't pass in the authentication parameters.
All the guides I've read online state that I should be able to connect with just the
isql -v asterisk-connector
command, but that's not happening for me.
I've been pulling my hair out for a few days on this, so any help or pointers in the right direction would be much appreciated.
Thanks in advance.
Edit:
I have turned on logging, and may have a clue. The username and password definitely aren't being passed in. Look:
[ODBC][27557][1455205133.129690][SQLConnect.c][3614]
Entry:
Connection = 0xac3080
Server Name = [asterisk-connector][length = 18 (SQL_NTS)]
User Name = [NULL]
Authentication = [NULL]
UNICODE Using encoding ASCII 'ISO8859-1' and UNICODE 'UCS-2LE'
DIAG [01000] [FreeTDS][SQL Server]Adaptive Server connection failed
DIAG [S1000] [FreeTDS][SQL Server]Unable to connect to data source
So User Name and Authentication here are [NULL]. It's obviously not picking up the username / password in odbc.ini or res_odbc.conf, but the question is why. I'll keep investigating :)
Edit2:
The OSQL utility returns:
[root#TestVM etc]# osql -S SQL2 -U MyUsername -P MyPassword

I would replace "Username" with "UID" and "Password" with "PWD" in your odbc.ini.... from FreeTDS Manual - Chapter 4 - Preparing ODBC:
The original ODBC solution to this conundrum employed the odbc.ini file. odbc.ini stored information about a server, known generically as a Data Source Name (DSN). ODBC applications connected to the server by calling the function SQLConnect(DSN, UID, PWD), where DSN is the Data Source Name entry in odbc.ini, UID is the username, and PWD the password. Any and all information about the DSN was kept in odbc.ini. And all was right with the world.
The ODBC 3.0 specification introduced a new function: SQLDriverConnect. The connection attributes are provided as a single argument, a string of concatenated name-value pairs. SQLDriverConnect subsumed the functionality of SQLConnect, in that the name-value pair string allowed the caller to pass — in addition the the original DSN, UID, and PWD — any other parameters the driver could accept. Moreover, the application can specify which driver to use. In effect, it became possible to specify the entire set of DSN properties as parameters to SQLDriverConnect, obviating the need for odbc.ini. This led to the use of the so-called DSN-less configuration, a setup with no odbc.ini.
Ok, so I solved it (pretty much). The password and username in my odbc files were being ignored. Because I was calling the DB queries from Asterisk, I was using a file called res_odbc.ini too. This contained my username and password also, and when I run the query from Asterisk, it conencts and returns the correct result.
In case it helps, here is my final working configuration.

Remember if you are using Centos 64 bit to modify the driver path to lib64. Most of the guides online have the wrong (for 64 bit) paths.
Good luck - it's a headache :)
I contacted the Nick Gorham the developer of unixODBC about this exact issue and he confirmed that isql is not reading the username/password from the config file
Hi Nick,
I think unixODBC is a great project but I was surprised to see that it
is insecure (or at least I don’t know how to use it properly).
When I connect to the database using the isql I have to type in the
password. On a shared server this is insecure because the
$ ps –aux
Command shows the password in clear.
Is there a fix for that? Can I put the password in a file readable
only by my user?
Thank you for your help.
The answer:
Hi,
It depends on the driver. Some can read the user and password from the
odbc.ini or ~/.odbc.ini file so you can store the password there.
isql is only designed as a simple test app, there is nothing stopping
you from modifying ilsq to pull the user and password from a file of
your choice, decrypting it if needed.
I was having a slightly different issue, but my google search lead me here. When trying to connect through isql, I was getting Login failed for user '' even though I had specified a user in my odbc.ini file
[SQLSERVER_SAMPLE]
Driver=ODBC Driver 17 for SQL Server
Server=SERVER
Database=DATABASE
Trusted_Connection=no
UID=USER
PWD=PASSWORD
I tried both UID and User, but both gave the same error. After reading #Andrei Sura's solution, I figured out that the username and password were being ignored.
My solution was to run isql -v SQLSERVER_SAMPLE USER PASSWORD even though the username and password were specified in the odbc.ini file - and it connected.

I have a default Teiid 12.2 installation on RHEL 8.
Now I'm trying to configure an ODBC connection that would be used by PHP.
This always results in an error "[unixODBC]received invalid response to GSSAPI negotiation: R"
This is my ODBC configuration
[TEIID12]
Driver = PostgreSQL
Trace = No
Description = PostgreSQL Data Source
Servername = servername
Port = 35432
Protocol = 7.4-1
UserName = someusername
Password = xxxx
Database = vdb
ReadOnly = no
ServerType = Postgres
ConnSettings =
UseServerSidePrepare=1
Debug=0
Fetch = 10000
A regular isql command also fails with the same information
isql -v TEIID12 someusername xxxx
Results in:
[08001][unixODBC]received invalid response to GSSAPI negotiation: R
[ISQL]ERROR: Could not SQLConnect
Additional information:
The same configuration used to work on a different Linux Distro (Ubuntu) but on this machine, kerberos was not configured. So I assume that this is influincing some sort of "preference".
The standalone-teiid.xml configuration has <ssl mode="disabled" /> for the odbc transport. And yet the GSS API errors occur.
In combination with the later, is it possible that the postgresql ODBC driver is requiring GSS to be used? Is there a setting in odbc.ini where this can be disabled?
On Ubuntu the driver version was 10.01, on RHEL it is 10.03
A solution that worked was to set the environment variable PGGSSENCMODE=disable in /etc/profile.
I'm actually facing an issue. I've installed pgbouncer on a production server, on which i've a Odoo instance and postgresql as well.
Perhaps :
In my logs, i'm having this :
2018-09-10 16:39:16.389 10123 WARNING C-0x1eb5478:
(nodb)/(nouser)#unix(18272):6432 pooler error: no such database: postgres

Here is the actual conf of pgbouncer :
pgbouncer_archive = host=127.0.0.1 port=5432 dbname=archive
admin_users = postgres
ignore_startup_parameters = extra_float_digits
With aswell, the default config (i've only added/edited this).
Why is he trying to connect on the postgres database ?
When i go back on the previous conf (without PGBouncer, just swapping from port 6432 to 5432), everything is working ....
Any idea ?
Thanks in advance !
I had the same issue, and in my situation. Maybe it will be usefull to somebody:
I have solved this by a few steps:
At the beginning of every request - your Framework or PDO (or else) running the initial query to check if database you asking is exists in the postgres data to process you request.
I have replaced the part of line "user=project_user password=mytestpassword" from the database section of pgbouncer.ini file. As I tested, if you replace this part - then the pgbouncer will use your userlist.txt file (or your selected auth), in my case, it was the userlist.txt.
Added the line "postgres = host=127.0.0.1 port=5432 dbname=postgres"
[databases]
postgres = host=127.0.0.1 port=5432 dbname=postgres
my_database = host=127.0.0.1 port=5432 dbname=my_database
My userlist.txt file looks like this (I am using auth_type = md5, so my password was in md5):
"my_user" "md5passwordandsoelse"
I have added my admin users to my pgbouncer.ini file:
admin_users = postgres, my_user
After all manipulations I advise you to check from which user u are running queries, by usin this simple query:
select current_user;
At the end, with this query you must to receive you selected username (in my case it was - my_user)
p.s. also I must to mention, that I was using 127.0.0.1 - because my pgbouncer is installed on the same server with postgres.
I searched for answers related to my question but not found what I'm looking for.
I have server with Linux CentOS 6.7. I need to connect to MS SQL Server 2005 on Windows Small Business Server 2003. In CentOS I installed FreeTDS and I managed to connect to SQL Server from terminal using this command:
# TDSVER=7.0 tsql -H ServerIPAdress -p 1433 -U username -P password
As far as I know this command bypass settings in freetds.conf.
Now I need to connect from PHP script. I'm using PDO extension and I tried this DSN string:
$db = new PDO("dblib:version=7.0;host=ServerIPAdress;dbname=Database;","username","password");
This leads me to first error:
Could not find driver
Ok, I understand that - my PHP 5.3.3 installation doesn't have installed PDO driver dblib.
My question: How can I install pdo_dblib driver in CentOS? Many tutorials and answers suggest to install through this command:
yum install php5-sybase
But that package doesn't exist:
No package php-sybase available.
If I check tsql configuration with command
tsql -C
I get these output:
Version: freetds v0.95
freetds.conf directory: /usr/local/etc
MS db-lib source compatibility: no
Sybase binary compatibility: no
Thread safety: yes
iconv library: yes
TDS version: 5.0
iODBC: no
unixodbc: yes
As I understand I need to configure FreeTDS:
./configure --enable-msdblib --with-pdo-dblib=/usr/local
But how can I configure FreeTDS after instalation? I tried to remove current version but I can't find way to do that. Also I tried to install another version but configuration doesn't change.
Any advice are appreciated.

I suspect that my username make problems because I have to use DOMAIN name followed by backslash before username when I connect to SQL Server 2005.

I succesfully made connection in PHP and now I can run queries. I added this line on top of my script: putenv("FREETDSCONF=/usr/local/etc/freetds.conf")

its a 32 bit linux machine having 32 bit db driver as well.
According to this IBM Support page, an IM004 SQLState on SQLAllocHandle relates to the new security feature.
Cause
The new security features introduced in DB2® Universal Database™ (DB2
UDB) Version 8.2 prevent users from using the database unless they
belong to the Windows® groups DB2ADMNS or DB2USERS.
Answer
Add the userid (the one used to execute the application) to either the
DB2ADMNS or DB2USERS group. Please refer to the link under "Related
Information" (below) for instructions on how to accomplish this.
Alternatively, there are a number of threads (e.g. Huge problems connecting to a DB2 database) which suggest setting the DB2INSTANCE environment variable to match the instance setting in your odbc.ini file for the DSN concerned, e.g.
export DB2INSTANCE=db2inst1
isql -v FS01DB2

You should copy /etc/freetds.conf to your home folder with dot before its name like this:
cp /etc/freetds.conf ~/.freetds.conf
Looks like it searches for config per user, I got the same problem recently.
Try creating freetds.conf file in /usr/local/etc
Creating a ~/.freetds.conf should work for you. It works fine for me
