Hi guys, I've an instance of Koha in lab test and I'm trying to enable ldap auth towards our active directory server (samba4 instance), but I'm experiencing some issues. Koha is correctly installed on an Ubuntu 16.04.6 LTS, fully updated. I read and followed this page [0], step by step, without any problems. Now, I've followed this step: 1. Open /etc/koha/sites/*biblioname*/koha-conf.xml 2. Enable LDAP: <useldapserver>1</useldapserver> 3. Insert settings as follow: <ldapserver id="ldapserver" listenref="ldapserver"> <hostname>ldaps://*IP-OF-DC*</hostname> <base>ou=Users,dc=*sub*,dc=*domain*,dc=*tld*</base> <user>cn=*user*,dc=*sub*,dc=*domain*,dc=*tld*</user> <pass>*password*</pass> <replicate>1</replicate> <update>1</update> <auth_by_bind>1</auth_by_bind> <principal_name>uid=%s,ou=*User*,dc=*sub*,dc=*domain*,dc=*tld*</principal_name> <mapping>record field names --> <userid is="uid"></userid> <password is="userpassword"></password> <email is="mail"></email> </mapping> </ldapserver> 4. Reload apache service After that, when I try to open the OPAC interface as well as staff interface, the follow errors appears: OPAC URL: Software error: Error reading file /etc/koha/sites/biblioname/koha-conf.xml. Try running this again as the koha instance user (or use the koha-shell command in debian) Compilation failed in require at /usr/share/koha/lib/C4/Auth.pm line 30.
