From LimeSurvey Manual
First define the LDAP server connections options in "application/config/ldap.php". For each server, the following options are available:
- $serverId: An integer that identifies this LDAP server. It is used in query definitions to bind a server to a specific query;
- $ldap_server[$serverId]['server']: The IP address or DNS name of the LDAP server. If you use SSL secured connections (LDAPs or LDAP+Start-TLS), this name must correspond to the server's Certificate CN (or SubjectAlternativeName);
- $ldap_server[$serverId]['protoversion']: Can be 'ldapv2' or 'ldapv3' depending on the protocol supported by your server. 'ldapv3' is the preferred protocol. However, if you want to use encrypted connections, note that LDAPs is supported in 'ldapv2' mode whereas Start-TLS is the encryption method for 'ldapv3';
- $ldap_server[$serverId]['encrypt']: Defines the encryption method used. 'ldaps' is supported for 'ldav2' servers, 'start-tls' for 'ldapv3' servers. The 'none' keyword is used for cleartext LDAP communications;
- Don't forget that for 'ldaps' or 'start-tls' encryption, the webserver must be able to check the LDAP server's certificate. Thus, you need to define your Certificate Authority in your openldap library (usually this is done in the /etc/openldap/ldap.conf file under linux).
- $ldap_server[$serverId]['referrals']: It is a boolean parameter that defines if referrals must be followed or not (use false for ActiveDirectory);
- $ldap_server[$serverId]['encoding']: It is an optional parameter which gives the encoding used by the LDAP directory to store strings. You usually do not need to setup this parameter as the default assumed encoding, 'utf-8', is the standard encoding for LDAP directories. However, if you're using Active Directory and having problems importing accentuated strings, then try to setup this parameter to the encoding used in you area (for instance 'cp850' for West Europe). You can refer to the "Character set of the file" drop-down list in the Import Token from CSV file GUI to have the full list of supported encodings.
