HPDMG1056E A registry initialization error received on DataPower appliance

Troubleshooting


Problem

When using Tivoli Access Manager (TAM) to authenticate incoming requests via AAA policy, the following errors may occur: 20130722T122320Z [tam][warn] tam(my_tam_object): tid(197327): Tivoli Access Manager message returned - '2013-05-22-08:23:20.603-04:00I----- 0x14C01420 AuthAPI ERROR mgr uraf MrDomainMan.cpp 307 0xf15feb70 HPDMG1056E A registry initialization error has occurred.' 20130722T122320Z [tam][warn] wsgw(my_service): tid(13461473)[request][10.69.102.107]: Tivoli Access Manager authorization client log message: TAM server error: azn_util_password_authenticate : HPDAC1980E Registry client returned a failure status.

Cause

When there exists two TAM clients on the appliance that use different TAM Active Directory (AD) configurations, there is the possibility for the wrong TAM configuration data to be used for authentication.

Before starting a TAM client on DataPower, it sets up the (shared) configuration files required by the TAM runtime libraries. These files contain TAM configuration information such as TAM policy and registry server names. When a second TAM client is started, these shared configuration files are rewritten to suit the TAM configuration of the second client.

The TAM Active Directory runtime libraries refer to the TAM policy and/or registry server information in these files while the client is running, and will therefore read different and potentially bad information if another TAM client has started since the first client has started.

Resolving The Problem

For DataPower firmware prior to 6.0.0.0, there is a limitation to have only one TAM Active Directory client on the appliance. As such, it is recommended to configure one TAM AD deployment PER appliance.

Note, DataPower 6.0.0.0 does not have this limitation as it contains enhancements to isolate each TAM client on the appliance to prevent this problem from occurring.
