Dear all, Active directory authentication in Koha is no more working after an upgrade from Koha 3.10 to Koha 3.12. Here is my koha-conf.xml file    <ldapserver id="ADserverFQDN" listenref="ADserverFQDN">  <hostname>ldap://ADserverFQDN:389</hostname>  <base>DC="domain",DC="domain"</base>  <user>cn="######",DC="domain",DC="domain"</user>  <pass>########</pass>  <replicate>1</replicate>  <update>1</update>  <auth_by_bind>1</auth_by_bind>  <principal_name>%s@"domain"</principal_name>  <mapping> <firstname    is="givenname"></firstname> <surname      is="sn"></surname> <address      is="postaladdress"></address> <city      is="l"></city> <zipcode      is="postalcode"></zipcode> <branchcode   is="branch">CPL</branchcode> <userid       is="samAccountName"></userid> <password     is="userpassword"></password> <email        is="mail"></email> <categorycode is="employeetype"></categorycode> <phone        is="telephonenumber"></phone>  </mapping>   </ldapserver> What is this update about "7973 Allow for new type of LDAP authentication"? My koha-conf.xml was working fine before the upgrade. Mesfin
