Strong authentication with SSL

Hi,

Sqlnet offers strong authentication with tcps (ssl) and I'm trying to make it work. My main interest is to authenticate the client with a X509 certificate.
In my setup I have two directories: Wallet_client and Wallet_server for the client wallet and server wallet. The steps are:

Code:

cd Wallet_client
1) orapki wallet create -wallet . -auto_login -pwd myclient99
2) orapki wallet add -wallet . -dn "CN=IVAN SAEZ" -keysize 1024 -self_signed -validity 365 -pwd myclient99
3) orapki wallet export -wallet . -dn "CN=IVAN SAEZ" -cert ../Wallet_server/ivan.cert
cd ../Wallet_server
4) orapki wallet create -wallet . -auto_login -pwd myserver99
5) orapki wallet add -wallet . -dn "CN=DBSERVER" -keysize 1024 -self_signed -validity 365 -pwd myserver99
6) orapki wallet export -wallet . -dn "CN=DBSERVER" -cert ../Wallet_client/db.cert
7) orapki wallet add -wallet . -trusted_cert -cert ivan.cert -pwd myserver99
cd ../Wallet_client
8) orapki wallet add -wallet . -trusted_cert -cert db.cert -pwd myclient99

In steps 7 and 8 client and server exchange their public keys.
The clients sqlnet.ora is:
Code:

WALLET_LOCATION = (SOURCE=
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY=/home/oracle/Wallet_client
)))
SSL_VERSION = 0
SQLNET.AUTHENTICATION_SERVICES = (TCPS,BEQ)
SSL_SERVER_DN_MATCH = TRUE
SSL_CIPHER_SUITES= (SSL_RSA_EXPORT_WITH_RC4_40_MD5)
SSL_CLIENT_AUTHENTICATION = TRUE
NAMES.DIRECTORY_PATH= (TNSNAMES,EZCONNECT)
TRACE_DIRECTORY_CLIENT = /home/oracle/Wallet_client
trace_level_client = USER
TRACE_FILE_CLIENT = trace_user

And the clients tnsnames.ora is:
Code:

DBSERVER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCPS)(HOST = 10.0.0.153)(PORT = 2484))
(CONNECT_DATA=
(SERVER = DEDICATED)
(SERVICE_NAME=IVAN2)
)
)
DBSERVER-CHECK =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCPS)(HOST = 10.0.0.153)(PORT = 2484))
(CONNECT_DATA=
(SERVER = DEDICATED)
(SERVICE_NAME=IVAN2)
)
(SECURITY=(SSL_SERVER_CERT_DN="CN=DBSERVER"))
)

The servers sqlnet.ora is:
Code:

SQLNET.AUTHENTICATION_SERVICES= (TCPS, BEQ)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
SSL_CLIENT_AUTHENTICATION = TRUE
SSL_CIPHER_SUITES= (SSL_RSA_EXPORT_WITH_RC4_40_MD5)
SSL_VERSION = 0
WALLET_LOCATION =
(SOURCE =
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY = /home/oracle/Wallet_server)
)
)
TRACE_DIRECTORY_SERVER = /u01/app/oracle/product/10r2/db_1/network/trace
trace_level_server = SUPPORT
TRACE_FILE_server = trace_server

The server's listener.ora content is:
Code:

TRACE_LEVEL_LISTENER = ADMIN
TRACE_FILE_LISTENER = listener
TRACE_DIRECTORY_LISTENER = /u01/app/oracle/product/10r2/db_1/network/trace
LOG_FILE_LISTENER = listener
LOG_DIRECTORY_LISTENER = /u01/app/oracle/product/10r2/db_1/network/log
LOGGING_LISTENER = ON

SID_LIST_SSL_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = IVAN2)
(SID_NAME = IVAN2)
(ORACLE_HOME = /u01/app/oracle/product/10r2/db_1)
)
)

#SSL_CLIENT_AUTHENTICATION = FALSE
SSL_LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCPS)(HOST = 10.0.0.153)(PORT = 2484))
)
WALLET_LOCATION = (SOURCE=
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY=/home/oracle/Wallet_server
)))

I also created a Oracle user to test the strong client authentication:

create user ivan identified globally as 'CN=IVAN SAEZ';
grant create session to ivan;

When I connect to the database, I set TNS_ADMIN to /home/oracle/Wallet_client first, with:

sqlplus isaez/pwd@dbserver-check

I can see (with a grep -i 'ssl cipher suite' trace_user*) that SSL is used: The final negotiated SSL Cipher Suite is:...

But when I try to use the clients x509 certificate to authenticate the connection:

sqlplus /nolog
connect /@dbserver-check

I get an error:
ERROR:
ORA-01017: invalid username/password; logon denied

I've wrestling with this problem a couple of hours and can't solve it. There is very few information on the net about orapki and ssl/tcps authentication. Maybe on Matelink but I don't have access to Metalink now.

Any ideas?

regards,

Ivan

Ivan, i've just repeated your setup successfully with one small difference. The database user must be created identified externally , not globally for ssl authentification. Identified globally works with enterprise users only ( also directory service ).

Maxim,

Yes, thank you!

Changing "create user ivan identified globally as 'CN=IVAN SAEZ'" to
"create user ivan identified externally as 'CN=IVAN SAEZ'" did indeed
solve the problem.

Ivan

Hi,

Did you check if ssl is installed? Use the adapters command to check it:
oracle@Asus:~ > adapters

Installed Oracle Net transport protocols are:

IPC
BEQ
TCP/IP
SSL
RAW
SDP/IB

Ivan

Yeah, I successed but I am not very satisfied, because there is no service:
Code:

And when I tried to do a tnsping on the client, I have :

Hi BBKing,

you'll need to add to the Listener.ora file a reference for a non SSL protocol in front of the TCPS protocol:

lnp_ssl =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.100)(PORT = 1521))
)
)
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCPS)(HOST = 192.168.2.100)(PORT = 2484))
)
)

I don't remember where I saw this but , this was a work around for that bug. If you search Metalink for the error :

TNS-12560 : TNS : error of protocol adapters

It should turn up the bug fix. or on OTN a discussion on this.

I found the reference in $ORACLE_HOME/relnotes/readmes

Unable to start LISTENER with TCP/IP SSL protocol
When adding a Listener with the endpoint "address" using the PROTOCOL=TCPS, you
need to have at least one other "address" specified for that listener with
PROTOCOL=TCP, and this "TCP" endpoint should precede the "TCPS" endpoint
address. (Bug 4089715)
To illustrate, the following entry is incorrect and the listener will not
start up properly (because the TCPS address is before the TCP address):
LISTENER_A =
(DESCRIPTION_LIST =
(DESCRIPTION =(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCPS )(HOST =
host.domain.com)(PORT = 2484 ))))
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP )(HOST =
host.domain.com)(PORT = 15151 ))))
)
The following entry is the correct way to do it:
LISTENER_A =
(DESCRIPTION_LIST =
(DESCRIPTION =(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP )(HOST =
host.domain.com)(PORT = 15151))))
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCPS )(HOST =
host.domain.com)(PORT = 2484))))
)
