[users@httpd] Apache on Windows with Active Directory Authentication

[Alvin Wong]

We have managed to configure Apache authenticate against AD with the following lines in .htaccess:     AuthName "Restricted Access"   AuthType Basic   AuthLDAPAuthoritative on   AuthLDAPURL "ldap://ad.mycompany.com.au:389/dc=mycompany,dc=com,dc=au?sAMAccountNAme?sub?(objectClass=user)"     AuthLDAPBindDN "cn=myusername, ou=userou, dc=mycompany, dc=com, dc=au"   AuthLDAPBindPassword mypassword   require valid-user   The problem is that after every 4-6 days, users are no longer able to access the website, requiring the computer to be restarted before it will continue to authenticate users .  The log shows:   [Tue Jul 18 14:59:37 2006] [warn] [client 128.250.196.11] [1276] auth_ldap authenticate: user myusername authentication failed; URI /website [ldap_search_ext_s() for user failed][Operations Error] [Tue Jul 18 14:59:40 2006] [warn] [client 128.250.196.11] [1276] auth_ldap authenticate: user myusername authentication failed; URI /website [ldap_search_ext_s() for user failed][Operations Error]   Any hints/solution would be greatly appreciated.  Thanks.
