I've tried searching the archives and can't seem to find the answer. When we use a correct username/password, the login page generates a Software Error: LDAP search failed to return object : 0000208F: LdapErr: DSID-0C090AC0, comment: Error processing name, data 0, v3839 at /usr/share/koha/lib/C4/Auth_with_ldap.pm line 97. Our conf file is set up like this: <useldapserver>1</useldapserver> <ldapserver id="ldapserver" listenref="ldapserver"> <hostname>ldaps://ldap.azag.gov</hostname> <base>"OU=XX,DC=XXXX,DC=XXX"</base> <user>ldapauth</user><!-- DN, if not anonymous --> <pass>XXXXXX</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$ --> <anonymous_bind>0</anonymous_bind> <principal_name>%s</principal_name> <mapping> <!-- match koha SQL field names to your LDAP record field names --> <userid is="sAMAccountName"></userid> <password is="userpassword"></password> <firstname is="givenname"></firstname> <surname is="sn"></surname> <branchcode is="">XXXX</branchcode> <categorycode is="">PT</categorycode> <email is="mail"></email> </mapping> </ldapserver> When logging in, we have to use "username@XXXX.XXX" instead of just "username". However, our emails are formatted "firstname.lastname@XXXX.XXX". I thought this might be the reason it's generating the error, but I'm not sure how to change the config file to reflect that. Or if I need to change the auth_with_ldap file. Thanks, Michael
