So basically anything that requires launching a subshell fails. I bet this: $ echo foo; (echo bar) foo bar will probably output only "foo". I'd expect it to produce an error message if it was having problems launching the subshell, but I suppose that might not happen if the shell it is trying to execute is something like /bin/false. Check the environment variables for anything odd, and run an instance of the shell with strace, logging to a file, and try starting a subshell. > ...specifically affects users that are defined in LDAP... What does the system think their login shell should be? (That alone wouldn't explain this, as the initial login would fail too, unless the login process is hard coded to use bash.) Sounds like it could alternatively be an SELinux problem, though I'd expect that to produce an error message. -Tom -- Tom Metro Venture Logic, Newton, MA, USA "Enterprise solutions through open source."
