Topic: Apache 2.4 Form based authentication with ldap as provider

[mckanth]

Hi,
I am trying to configure Apache 2.4 with form based authentication which is new in 2.4 and LDAP as provider. I get the login page and once I enter my ldap credentials i get the error

(70023)This function has not been implemented on this platform: AH01277: LDAP: Unable to add rebind cross reference entry. Out of memory?
We are using Active Directory as ldap server.
Can somebody please help me figure out what is wrong.
Are ldap modules not built properly for form based authentication? here is the configuration

<IfModule util_ldap.c>
AuthType form
AuthName Security-Admin
ErrorDocument 401 /authn/login.html
AuthFormProvider ldap
<IfModule mod_authnz_ldap.c>
AuthLDAPURL "ldap server url"
AuthLDAPBindDN "CN details"
AuthLDAPBindPassword "password"
Require valid-user
</IfModule>
</IfModule>
</LocationMatch>

Please help.

Thanks in advance
Chandra

AuthzLDAPAuthoritative should be off for
require valid-user. http://httpd.apache.org/docs/2.2/mod/mod_authnz_ldap.html#authzldapauthoritative

use the password without the quotes.

Hi,
i ran into the same problem and after a little bit of digging around, i found a solution that worked for me..

I firstly searched about ldap referrals and the options to turn this off in apache..

Turning this off solved the problem for me. it is a directive of the mod_ldap module
