http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12757 mod_ldap cache tries to open an existing shared memory file Summary: mod_ldap cache tries to open an existing shared memory file Product: Apache httpd-2.0 Version: HEAD Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Other Modules AssignedTo: bugs@httpd.apache.org ReportedBy: [EMAIL PROTECTED] File: /modules/experimental/util_ldap_cach.c apr_status_t util_ldap_cache_init(apr_pool_t *pool, apr_size_t reqsize) { #if APR_HAS_SHARED_MEMORY apr_status_t result; - result = apr_shm_create(&util_ldap_shm, reqsize, "/tmp/ldap_cache", pool); + result = apr_shm_create(&util_ldap_shm, reqsize, NULL, pool); if (result != APR_SUCCESS) { return result; } pool); #endif .... } The ldap cache used by mod_ldap and mod_auth_ldap tries to create a shared memory file for each process forked. The problem is that only the first process is able to create the file, all the other processes fail to create the file because it already exists. This disables caching on all processes other than the initial process. Caching LDAP authentication is essential as this is a slow task, especially with Microsoft Active Directory. One solution on linux is to use an anonymous shared memory file (fileName is NULL) but apparently anonymous shared memory is not supported on other platforms. I assume all processes should share a single cache. Would anonymous shared memory create a new file for each process? If this is not desired, only the first process should create the file and all the other processes should attach to in. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
