Description
When the TIBCO iProcess Engine is started the message below may be reported in the $SWDIR/logs/process directory _stderr files, such as RPC_TCP_LI_1_stderr, even though the iProcess Engine processes start successfully,
Cannot register service: RPC: Authentication error; why = Client credential too weak
Cannot register service: RPC: Authentication error; why = Client credential too weak
Issue/Introduction
Starting iProcess Engine reports cannot register service: RPC: Authentication error; why = Client credential too weak
Environment
Linux
Resolution
A change was made in iProcess Engine 11.4.0 to provide ipv4 support for rpcbind on Linux. The result of this change means the functionality within the iProcess Engine will initially try to bind using unsecure mode which results in the message being written to the _stderr files. If the bind fails and reports the message, the iProcess Engine will then attempt to bind in secure mode and if successful continue the start-up of the process.
The message "Cannot register service: RPC: Authentication error; why = Client credential too weak" can be misleading on Linux installations since iProcess Engine version 11.4.0.
