Hi, I've a technical question about ldap. My connexion with the ldap is enabled. The mapping is correct but we would like to use "SupannAliasLogin" instead of "uid". Why? Our uid is like this [year of entry in the school]+supannAliasLogin example:2012desseauxs 2012:year of entry in the school desseauxs:SupannAliasLogin I don't know how to do and i i have to change the principal name Actually, we have the following configuration <ldapserver id="ldapserver" listenref="ldapserver"> <hostname>*******</hostname> <base>ou=people,dc=ecp,dc=fr</base> <user>cn=syncrepl,ou=applications,dc=ecp,dc=fr</user> <pass>******</pass> <replicate>1</replicate> <update>1</update> <auth_by_bind>1</auth_by_bind> <principal_name>uid=%s,ou=people,dc=ecp,dc=fr</principal_name> <mapping> <firstname is="givenname"></firstname> <surname is="sn"></surname> <address is="">Ecole Centrale Paris</address> <city is="">Chatenay-Malabry</city> <zipcode is="">92290</zipcode> <branchcode is="">ECAM</branchcode> <userid is="uid"></userid> <password is="userpassword"></password> <cardnumber is="ecpbadgenumber"></cardnumber> <email is="mail"></email> <categorycode is="supannetudiplome">employee</categorycode> <phone is="telephonenumber">903-566-7654</phone> <dateenrolled is="">2012-09-01</dateenrolled> <dateexpiry is="">2013-09-01</dateexpiry> </mapping> </ldapserver> Many thanks samuel
