hi,Jens: I did guess that you should be off for your business trip or holidays , :-) I think basedn and binddn is the same in my vldap.h and slapd.conf, and if i have the below entry tree in my openldap through ldapbrowser:
dc=koal,dc=com | ->ou=people | -> ou=net.koal.com |->uid=postmaster ->uid=test and my slapd.conf: database ldbm suffix "dc=koal,dc=com" rootdn "cn=root,ou=people,dc=koal,dc=com" rootpw xxxxx ( here is the same with the password in vldap.h) and my vldap.h: #undef OLD_VLDAP #define VLDAP_SERVER "localhost" #define VLDAP_PORT LDAP_PORT #define VLDAP_USER "cn=root,ou=people,dc=koal,dc=com" #define VLDAP_PASSWORD "xxxxx" ( here is the same with the password in slapd.conf) #define MAX_BUFF 500 #ifdef OLD_VLDAP #define VLDAP_BASEDN "ou=Subs, o=vpop" #else #define VLDAP_BASEDN "ou=people,dc=koal,dc=com" #endif I test the pop3 authentication : [EMAIL PROTECTED] root]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK <[EMAIL PROTECTED]> user test +OK pass test Error: No such object matched DN: "ou=people,dc=koal,dc=com" -ERR authorization failed Connection closed by foreign host. and then maillog reports: Jul 16 14:39:29 mailserver vpopmail[1244]: vchkpw-pop3: vpopmail user not found test@:127.0.0.1 if i test the pop3 with a domain that doesn't exsits : [EMAIL PROTECTED] root]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK <[EMAIL PROTECTED]> user [EMAIL PROTECTED] +OK pass test Error: No such object matched DN: "ou=people,dc=koal,dc=com" -ERR authorization failed then maillog reports: Jul 16 14:42:06 mailserver vpopmail[1261]: vchkpw-pop3: vpopmail user not found [EMAIL PROTECTED]:127.0.0.1 it seems that i should submit the correct and complete email add: [EMAIL PROTECTED] then i test : [EMAIL PROTECTED] root]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK <[EMAIL PROTECTED]> user [EMAIL PROTECTED] +OK pass test -ERR aack, child crashed and then maillog reports nothing about this failed login. it seems that the vchkpw has recognized this [EMAIL PROTECTED] ,but child crashed error is occured. what's happened?
