This is a Python CGI script that lets ldap users change their own ldap passwords via a web interface.

If users with same UID and same oldpassword are found in other OUs, those passwords are updated too.


To install the script, simply extract all the repository contents into a folder under your document root. No paths need to be configured. Only make sure that the location is reachable via HTTPS. If used with Apache2, this module is required: a2enmod authnz_ldap

Configure LDAP settings for your LDAP server in

ldap_proto = 'ldap://'
ldap_server = 'localhost'
ldap_basedn = 'dc=ldap,dc=freiesnetz,dc=at'
ldap_userdn = 'ou=Users' +','+ ldap_basedn
ldap_bind_attr = 'uid'

Configure LDAP settings for your LDAP server in .htaccess:

AuthLDAPBindDN UID=bind,OU=Users,DC=ldap,DC=freiesnetz,DC=at
AuthLDAPBindPassword ldapbindpassword
AuthLDAPURL ldap://localhost/OU=Users,DC=ldap,DC=freiesnetz,DC=at?uid


This is a majorly for ldap-support rewritten version of a script originally developed by Dirk Boye. See dirkboye/mailpw_change at GitHub for the original source code.


  • Q: Can I use the script via unencrypted HTTP?
    A: No, HTTPS is hard-coded. So unless you change that in the code, you can't. And honestly, you really shouldn't.

  • Q: Do I need to put the script in /cgi-bin/?
    A: In most cases, no. The script comes with an .htaccess that enables CGI execution for the current directory. Generally, that should work. If not, your administrator may have disabled option overriding in which case you actually need to put it in /cgi-bin/. But in most cases (and especially on Uberspaces) it should work just fine.

  • Q: I only get an error 500 and the log file says something about suEXEC policy violation. How do I fix that?
    A: Make sure both the as well as the containing directory have the permissions 0755. Any higher permissions will usually result in that error. If you have trouble finding the root cause, possibly a look at journalctl -b will help you.
