Hi all, We are currently evaluating koha for our university. Right now, I’m trying to configure ldap authentication. I followed the following guides: https://openschoolsolutions.org/koha-ldap-setup/ https://perldoc.koha-community.org/C4/Auth_with_ldap.html I did the following configuration in /etc/koha/sites/<library name>/koha-conf.xml <useldapserver>1</useldapserver> <ldapserver id="ldapserver" listenref="ldapserver"> <hostname>ldap://ldap.domain.ch</hostname> <base>ou=users,DC=domain,DC=ch</base> <user>CN=srvc-koha,OU=unit,DC=domain,DC=ch</user><!-- DN, if not anonymous --> <pass>somepass</pass><!-- password, if not anonymous --> <replicate>1</replicate> <!-- add new users from LDAP to Koha database --> <update>1</update> <!-- update existing users in Koha database --> <auth_by_bind>1</auth_by_bind> <!-- set to 1 to authenticate by binding instead of password comparison, e.g., to use A$ --> <principal_name>%s@domain.ch</principal_name> <update_password>0</update_password> <mapping> <!-- match koha SQL field names to your LDAP record field names --> <firstname is="givenname" ></firstname> <surname is="sn" ></surname> <userid is="uidNumber" ></userid> <email is="mail" ></email> <phone is="telephonenumber"></phone> </mapping> </ldapserver> I’m trying to login to OPAC, but get the error message "You entered an incorrect username or password.” and the log file /var/log/koha/<library name>/opac-error.log is still empty. How can I debug the ldap authentication in koha? Best, Patric
