Hello, I recently added Kerberos authentication to my LDAP server, and I am trying to connect the other servers to it.I have a server running Davical shared calendar, and I hope to get it working with my LDAP server again after Kerberos integration. Here is my configuration which was working before the integration and my source is "http://wiki.davical.org/w/Configuration/LDAP#Kerberos_Authentication" $c->authenticate_hook['config'] = array( 'host' => 'ldap.domain.com', //host name of your LDAP Server 'port' => '389', //port// 'bindDN' => 'cn=admin,dc=domain,dc=com', //DN to bind request to this server (if required)// 'passDN' => 'password', //Password of request bind 'baseDNUsers' => 'ou=People,dc=domain,dc=com', //where to look for valid user 'filterUsers' => 'objectClass=*', //filter which must validate a user according to RFC4515, i.e. surrounded by brackets 'protocolVersion' => 3, // important for simple auth (no sasl)// 'startTLS' => true, // securing your LDAP connection 'i_use_mode_kerberos' => "i_know_what_i_am_doing", My slapd error logs:Jan 31 23:40:00 ldap slapd[1059]: conn=1273 fd=43 ACCEPT from IP=203.28.247.193:56887 (IP=0.0.0.0:389)Jan 31 23:40:00 ldap slapd[1059]: conn=1273 op=0 BIND dn="" method=128Jan 31 23:40:00 ldap slapd[1059]: conn=1273 op=0 RESULT tag=97 err=0 text=Jan 31 23:40:00 ldap slapd[1059]: conn=1273 op=1 SRCH base="ou=People,dc=domain,dc=com" scope=2 deref=0 filter="(objectClass=*)"Jan 31 23:40:00 ldap slapd[1059]: conn=1273 op=1 SRCH attr=uid modifyTimestamp cn mailJan 31 23:40:00 ldap slapd[1059]: conn=1273 op=1 SEARCH RESULT tag=101 err=32 nentries=0 text=Jan 31 23:40:00 ldap slapd[1059]: conn=1273 op=2 UNBIND My OLC configuration:root@ldap:/var/log# ldapsearch -LLLQY EXTERNAL -H ldapi:/// -b cn=config "(|(cn=config)(olcDatabase={1}hdb))"dn: cn=configobjectClass: olcGlobalcn: configolcArgsFile: /var/run/slapd/slapd.argsolcAuthzRegexp: {0}uid=([^,]+),cn=domain.com,cn=gssapi,cn=auth uid=$1 ,ou=people,dc=domain,dc=comolcLogLevel: statsolcPidFile: /var/run/slapd/slapd.pidolcSaslRealm: DOMAIN.COMolcToolThreads: 1 dn: olcDatabase={1}hdb,cn=configobjectClass: olcDatabaseConfigobjectClass: olcHdbConfigolcDatabase: {1}hdbolcDbDirectory: /var/lib/ldapolcSuffix: dc=domain,dc=comolcAccess: {0}to attrs=userPassword,shadowLastChange by anonymous auth by * no neolcAccess: {1}to dn.subtree="ou=krb5,dc=domain,dc=com" by dn="c n=adm-srv,ou=krb5,domain,dc=com" write by dn="cn=kdc-srv,ou =krb5,domain,dc=com" read by * noneolcAccess: {2}to attrs=loginShell,gecos by self write by users read by * noneolcAccess: {3}to dn.base="" by * readolcAccess: {4}to * by users read by * noneolcLastMod: TRUEolcRootDN: uid=admin,ou=people,domain,dc=com
Any suggestion to fix the binding and get my search working again with kerberos authentication ? Thanks.
