installing OID Preview 1

Download oracle-oid-
Download oracle-xe-univ-

Install the rpm
# rpm -i oracle-*.i386.rpm

In SLES 10, there is no /bin/cut, let’s create a link as root to avoid a mistake when running
# ln -s /usr/bin/cut /bin/cut

Run the configure script as root
# /etc/init.d/oracle-oid configure
That’s all folks! It created an Oracle XE 10gR2 database, and configured a running database. Excellent!

LDAP Server is running and configured.

$ ldapsearch  cn=orcladmin dn
cn=orcladmin, cn=Users, dc=com

There is a nice video to run on linux : oracleauthenticationservices_demo.vvl
Save the file, set the display, then

$ chmod +x oracleauthenticationservices_demo.vvl
$ ./oracleauthenticationservices_demo.vvl

It shows also how to use Oracle LDAP Server OID to identify your Linux users with the preview of Oracle Authentication Service

Configure OID with SSL

First you need to install OID. Check the Installation Guide, the Doc and download the Software. If you do not need the dbconsole, stop it (emctl stop dbconsole) and remove the oracle_home/hostname_sid directory

Once you have a running OID, test it with ldapsearch. For this workshop, I use two servers and two usernames. Having the client and the server sharing the same wallet is not a good idea. If you have an Oracle Database running as user oracle, prefer using a different user for OID installation. By installing OID, I specified the following staticports.ini (missing from CD, bug 5936042) :

Oracle HTTP Server port  = 44000
Oracle HTTP Server Listen port  = 44001
Oracle HTTP Server SSL port  = 44002
Oracle HTTP Server Listen (SSL) port  = 44003
Oracle HTTP Server Diagnostic port  = 44004
Java Object Cache port  = 44005
DCM Discovery port  = 44006
Oracle Notification Server Request port  = 44007
Oracle Notification Server Local port  = 44008
Oracle Notification Server Remote port  = 44009
Application Server Control port  = 44010
Application Server Control RMI port  = 44011
Oracle Management Agent port  = 44012
Log Loader port  = 44013
ASG port  = 44014
Oracle Internet Directory port  = 44015
Oracle Internet Directory (SSL) port  = 44016
Oracle Certificate Authority SSL Server 
    Authentication port  = 44017
Oracle Certificate Authority SSL Mutual
    Authentication port  = 44018

Ok, let’s do the search from another server

lsc@dbserver01 $ ldapsearch -h oidserver01 -p 44015 -z 1
orclreplicaid=oidserver01_oid1014,cn=replication configuration
ldap_search: Sizelimit exceeded

Now let’s try with SSL. First, with no authentication (-U 1).

lsc@dbserver01 $ ldapsearch -h oidserver01 -p 44016 -z 1 -U 1
orclreplicaid=oidserver01_oid1014,cn=replication configuration
ldap_search: Sizelimit exceeded

Fine. Let’s create the wallets. You need a wallet for your client (lsc@dbserver01), a wallet for your server (ldapusr@oidserver01). Create a certification request for CN=lsc,cn=users,dc=yourdomain,dc=com, export your user certificate from your client wallet (lsc@dbserver01) and import it as a trusted certificate in your oid wallet (ldapusr@oidserver01). It is the same procedure as described in the user identified externally with SSL certificate post

Then, launch oidadmin (you can launch it from a pc client), and configure the OID for ssl.
In Oracle Internet Directory Servers –> cn=orcladmin@oidserver01 –> Server Management –> Directory Server. Right click on Configuration Set1 and chose Create Like. In the Configuration Set2, chose the SSL Settings, specify SSL Client and Server Authentication, SSL only, file://etc/ORACLE/WALLETS/lsc, SSL Port 44019. Apply. Quit

Start a second instance with oidctl where oid1014 is your SID

ldapusr@oidserver01 $ oidctl connect=oid1014 server=oidldapd
    instance=2 configset=2 start

Check the status :

ldapusr@oidserver01 $ oidctl connect=oid1014 server=oidldapd
oidctl:Checking Oracle Internet Directory Processes ...

    Process oidmon is alive as PID = 16191 

    Checking OIDLDAPD instance 1  ...
    Process oidldapd (dispatcher) is alive as PID = 16197
        port=44015 sslport=44016
            oidldapd (server)     is alive as PID = 16206

    Checking OIDLDAPD instance 2  ...
    Process oidldapd (dispatcher) is alive as PID = 16422
            oidldapd (server)     is alive as PID = 16426

    Checking ODISRV instance 1  ...
    Process odisrv   is alive as PID = 16203

so far not bad!

Let’s pray !

$ ldapbind -h -p 44019  -U 3
    -P mywalletpasswd -W file://etc/ORACLE/WALLETS/lsc  
    -D cn=orcladmin -w myorcladminpasswd
bind successful

What a satisfaction 😀 I have being failing on this for days. Mostly getting meaningless message like UnKnown Error Encountered. You cannot start anything with that error. It could be a wallet path error, a wallet password error, a non-authorized certificate, a certification authority problem, and many other errors. Really poor error messaging there. One may argue that meaningless error message on unsuccessful login does increase the security, but well, it is a nightmare to debug 😮

Now I need to stop the non-secure part of it :

ldapusr@oidserver01 $ oidctl connect=oid1014 server=oidldapd
    instance=1 stop

Added 29.3.2007
If I want to use a SSL to authentify my user, I must create a user, for example with the Security Console http://oidserver01:44000/oiddas/ui/oideushome, which matches my certificate.

ldap day 2

what can I do with LDAP?
what is the difference between LDAP and Oracle Internet Directory?

Well, there is quite a lot of interresting documents, pictures and faq on otn :

  • OTN Directory homepage
  • Directory Admin guide
  • Identity Management ReferenceLDAP is a directory server, the info are stored in an Oracle database.

    When you download application server (about 2Gb), you get a fully functionnal database preconfigured and an ldap server running.

    To start the admin tool, just type oidadmin in the command line.

    The password to use is the same as ias_admin and the username is orcladmin

  • ldap server

    My ldap server is up and running on my notebook with SLES9.

    Next, next, next, install. That is it.

    Oracle Application Server creates a database and start the Oracle Internet Directory – understand LDAP server – automatically.

    It can then be configured with the web interface.
