Known Problems and Limitations in HP-UX AAA Server A.07.01

Decreased RADIUS response time under heavy load due to increased CPU consumption.

	NOTE: This problem occurs with the HP-UX AAA Server A.07.01 on HP 9000 systems running HP-UX 11i v2 or HP-UX 11i v3. HP 9000 systems running HP-UX 11i v1, and HP Integrity® systems running HP-UX 11i v2 or HP-UX 11i v3 are not affected.

Workaround 1: Utilize the pthread environment variable that minimizes pthread overhead for the HP-UX AAA Server in the environment where the radiusd daemon is launched:

$export PTHREAD_FORCE_SCOPE_SYSTEM=ON

Workaround 2: Install the PHCO_35997 pthread library patch on HP 9000 systems running HP-UX 11i v2, or PHCO_37477 on HP 9000 systems running HP-UX 11i v3. These patches are available at:

The HP-UX AAA Server leaks memory when the SQL Access feature uses the MySQL Unix ODBC/MySQL client to interact with a MySQL database.

	NOTE: This problem occurs with the HP-UX AAA Server A.07.01 on HP 9000 systems running HP-UX 11i v2 with the PHSS_31849 (or later) patch only. HP 9000 systems running HP-UX 11i v1 or HP-UX 11i v3, and HP Integrity systems running HP-UX 11i v2 or HP-UX 11i v3 are not affected.

Workaround: Install PHSS_34858 (linker + fdp cumulative patch) on the HP 9000 system running HP-UX 11i v2, where the radiusd daemon is launched.

The User Database Administration Manager is not compatible with HP-UX Apache Web Server B.2.0.59.00.

Workaround: HP-UX Apache Web Server B.2.0.59.00 does not include DB.php, which is required for the User Database Administration Manager. Upgrade the HP-UX Apache Web Server to B.2.0.59.04 or later. The latest version of HP-UX Apache Web Server is available at:

Using stored procedure output parameters with MySQL databases will result in NULL values for SQL Access output mappings. Input mappings can be processed normally with MySQL stored procedures.

Workaround: Utilize direct SQL statements for SQL Actions requiring output data from MySQL databases.

The HP-UX AAA Server does not recognize realm aliases for local realms configured with local user file storage.

Workaround: Configure separate realms for each alias.

The HP-UX AAA Server A.07.01 loads all shared libraries in the /opt/aaa/aatv/ directory when starting. Libraries with unresolved external references will cause the startup to fail. User-created libraries for previous versions of the product may also fail during execution. Updating the installation replaces only the libraries originally installed with the product—any user-created libraries will remain.

Workaround: Remove any user-created shared libraries from the /opt/aaa/aatv/ directory before starting the HP-UX AAA Server.

Unsupported browsers, including Netscape Navigator 7.0 and Mozilla 1.2.X periodically display various Server Manager icons, buttons, and default values incorrectly.

Workaround: Use a supported browser version with Server Manager.
