If nscd is not running we have: - dbus (messagebus service) fails to start and so also hal - tcsh reports 'broken pipe' for any command issued - 'su - <user>' doesn't work - login from console fails because of the shell. If ncsd is running: - dbus still fails to start (because the service starts at "22", before ncsd (it starts at "30")) while all other problems seem to disappear. We have investigated for a while and the problems are reproducible with: - system just installed, - ldap configurated with SSL support - ncsd stopped everythings works, - yum update nss_ldap -> breaks ldap as described - start ncsd -> fixes the problems as described I don't think this problem is that already reported as https://bugzilla.redhat.com/show_bug.cgi?id=447881 Sorry if it is not an SL specific issue and hope this can help someone else. thanks, Matteo -- ________________________________________________________________________ Dott.
