http://issues.apache.org/bugzilla/show_bug.cgi?id=42690 Summary: realm is not set for each configured directory when digest authentication is used Product: Apache httpd-2 Version: 2.2.3 Platform: Other OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: mod_auth_digest AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] When the following configuration is set in httpd.conf file: <Directory "/var/www/webapps/*/cgi-bin"> AllowOverride None Order allow,deny Allow from all AuthType Digest AuthDigestDomain /var/www/webapps/*/cgi-bin/ AuthName My_Realm AuthUserFile /etc/apache/.htdigest AuthGroupFile /etc/apache/.htgroups Require group users </Directory> <Directory "/var/www/webapps/admin/cgi-bin"> AuthDigestDomain /admin/cgi-bin/ Require group admins </Directory> "Segmentation fault (11)" is logged in Apache error log because realm (AuthName) for /var/www/webapps/admin/cgi-bin directory is not initialized. When AuthDigestDomain directive is not set for this directory then Apache work correctly. Here is gdb output: # gdb httpd -d /source/ GNU gdb 5.2.1 Copyright 2002 Free Software Foundation, Inc.
