On the ppc64 and s390 architectures radiusd fails to start emitting these errors: Error: /etc/raddb/mods-enabled/echo[34]: Cannot read output pairs if wait = no Error: /etc/raddb/mods-enabled/echo[34]: Instantiation failed for module "echo" The problem is due to using the wrong type in the module config struct passed to the config file parser. The type was declared as bool but conffile.c treats PW_TYPE_BOOLEAN as an int. This causes an if test to fail because the bool value is not true when it should be. This is in rlm_exec.c. I found 1 other module which had bool's declared for PW_TYPE_BOOLEAN config items, rlm_pap.c. Attached is a git formatted patch which changes 3 bool declarations to int and include a full explanation in the git commit message. The attachment can be applied with git apply. -- John
