Operating system authentication for a database administrator typically involves establishing a group on the operating system, granting DBA privileges to that group, and then adding the names of persons who should have those privileges to that group. (On UNIX systems, the group is the dba group.
ALLOWED_LOGON_VERSION_SERVER parameter to the value 11 or lower. (Be aware that earlier releases used the value 8 as the default. Greatest level of compatibility: To configure the server to generate all three password versions, the 12C password version, the 11G password version, and the DES-based 10G password version whenever a new account is created or an existing account password is changed, set the SQLNET.
These application users are known to an application but unknown to the database. The CLIENT_IDENTIFIER attribute can capture any value that the application uses for identification or access control, and passes it to the database. The CLIENT_IDENTIFIER attribute is supported in OCI, JDBC/OCI, or Thin driver.
If you use a network authentication service, then some special considerations arise for network roles and database links. If network authentication services are available to you, then Oracle Database can accept authentication from the network service.
After that, we will replace the Directory Services certificate on the PSC. This means any of the web services the PSC is providing are now using a VMCA issued certificate. That is covered in Part 12. This will bring our two installations up to the same level. Because we are using the VMCA for all of our certificates, we’ve also re-issued the PSC’s machine SSL certificate to one issued by the VMCA. In the next installment we will assume you can NOT use the VMCA for compliance reasons, and will replace the PSC’s machine SSL certificate with a trusted one.
JRE is used in many products, so a wide range of products are affected. The full patch matrix seems to include products that didn’t made the affected products list. In case you missed it, VMware has released a number of product updates to address critical vulnerability in JRE. So carefully review the full security bulletin, as a majority (if not nearly all) VMware products are affected. You can read the full bulletin here. So keep your eyes out for another VMware announcement when the patches become available. In many cases patches are “pending” such as vCenter 6. The bulletin details which product version you need to be running to be patched.
Pem first before I can install the certificate on the client (which is SLES server) and finally Q2: what is the best way to install this certificate on the server so my php application can access it and do its job. Q1: Do I need to convert from. Note that on the SLES server we need to connect to different LDAP servers.
When they log in, they will be prompted to change their password, ensuring that the password versions required for authentication in Exclusive Mode are generated by the server. (For more information about how Exclusive Mode works, see the usage notes for the SQLNET. ALLOWED_LOGON_VERSION_SERVER parameter in Oracle Database Net Services Reference.
The external password store of the wallet is separate from the area where public key infrastructure (PKI) credentials are stored. Consequently, you cannot use Oracle Wallet Manager to manage credentials in the external password store of the wallet. Instead, use the command-line utility mkstore to manage these credentials.
Examples of application compatibility issues are applications that force passwords to uppercase before using them to authenticate to the Oracle server, or different application modules being inconsistent about case sensitivity when sending credentials to start a database session. For greater security, Oracle recommends that you use case sensitivity in passwords. However, if you have compatibility issues with your applications, then you can use the SEC_CASE_SENSITIVE_LOGON parameter to disable password case sensitivity.
See Ensuring Against Password Security Threats by Using the 12C Password Version for more information. Passwords hashed using the 12C password version. To verify the user’s password and enforce case sensitivity in password creation, Oracle Database uses the 12C password version, which is based on a de-optimized algorithm that involves Password-Based Key Derivation Function (PBKDF2) and the SHA-512 cryptographic hash functions.
This avoids the overhead of setting up a separate session and separate attributes for each user, and enables reuse of sessions by the application. With this approach, sessions can be reused by multiple users by changing the value of the CLIENT_IDENTIFIER attribute, which captures the name of the real application user. When the CLIENT_IDENTIFIER attribute value changes, the change is added to the next OCI, JDBC/OCI, or Thin driver call for additional performance benefits.
