I’ve got a problem with a site after ldap authentication.
Windows server with apache – httpd-ssl.conf:

<VirtualHost *:443>
    ServerAdmin [email protected]
    DocumentRoot "E:/Intranet/testpage/"
    ServerName testpage
    ErrorLog "logs/ourproject.error.log"
    CustomLog "logs/ourproject-access.log" common

    <Location />
        Require host testpage
        AuthType Basic
        AuthName "USE YOUR WINDOWS ACCOUNT"
        AuthBasicProvider ldap
        Require valid-user
        AuthLDAPBindDN "CN=test,OU=Service-Accounts,OU=Administration,DC=test,DC=dc"
        AuthLDAPBindPassword "password"
        AuthLDAPURL "ldap://ad-server.test.dc/ou=Region_MSR,dc=test,dc=dc?sAMAccountName?sub?(objectClass=*)"
    </Location>
    
#   <Directory E:/Intranet/alexianer-intern/>  
#            Options Indexes FollowSymLinks MultiViews
#            AllowOverride AuthConfig
#    </Directory>

    SSLEngine on
    SSLCertificateFile "${SRVROOT}/conf/test.crt"
    SSLCertificateKeyFile "${SRVROOT}/test.pem"

    <FilesMatch ".(cgi|shtml|phtml|php)$">
        SSLOptions +StdEnvVars
    </FilesMatch>
    <Directory "${SRVROOT}/cgi-bin">
        SSLOptions +StdEnvVars
    </Directory>

    BrowserMatch "MSIE [2-5]" 
             nokeepalive ssl-unclean-shutdown 
             downgrade-1.0 force-response-1.0

    CustomLog "${SRVROOT}/logs/ssl_request.log" 
              "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x "%r" %b"
</VirtualHost> 

The apache server hosts a multi-domain typo3-site. All domains are accessible but one – it’s protected by ldap authentication, which works.
But after successfull AD-login, I get an internal server error – other domains from the same installation work fine.

Error-Log: [ldap:error] [pid 3580:tid 1500] (70023)This function has not been implemented on this
platform: AH01277: LDAP: Unable to add rebind cross reference entry. Out of memory?

Inserting “LDAPReferrals Off” results in

Not Found
The requested URL /aktuelles was not found on this server.

Tried also with alias, which didn’t work.

Any suggestions!
Thanks a lot!
