Description Ian Mortimer 2003-07-21 02:47:29 UTC
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: After the errata upgrade on our NIS server some automount map entries were no longer being matched. They showed up in `ypcat -k auto.home' but not in `ypmatch user auto.home'. All the entries that failed had a space followed by one or more tabs between the two fields of the map. All other entries had either all spaces or all tabs. Changing the failing entries to all spaces or all tabs fixed the problem. Version-Release number of selected component (if applicable): ypserv-2.8-0.73E How reproducible: Always Steps to Reproduce: 1. Create a NIS map with two fields separated by white space 2. For some entries separate the fields with a space followed by one or more tabs 3. do 'ypmatch name map_name' for the mixed white space entries Actual Results: ypmatch returns: Can't match key _user_ in map _map_. Reason: No such key in map Expected Results: ypmatch should have shown the entry since ypcat -k _map_ showed it. This worked fine prior to the errata upgrade. Additional info: This is not serious since it's easily worked aroubd but in an environment like ours where NIS maps have been imported from other OSes and maintained by several generations of admins it might not be easy to see what the problem is. It was only after looking at the maps using vi in :list mode that I was able to see it. Otherwise the misbehaving entries looked identical to the good ones.

This problem is not benign. Existing and obviously correct NIS maps unexpectedly stopped working and it was very hard to trace the problem down to particular combinations of spaces and tabs in /etc files. Most text editors do not visually distinguish between spaces and tabs, and, even worse, arbitrary convert tabs into spaces and spaces into tabs. K.O.

Red Hat Linux and Red Hat Powertools are currently no longer supported by Red Hat, Inc. In an effort to clean up bugzilla, we are closing all bugs in MODIFIED state for these products. However, we do want to make sure that nothing important slips through the cracks. If, in fact, these issues are not resolved in a current Fedora Core Release (such as Fedora Core 5), please open a new issues stating so. Thanks.
