Hi I have Samba 3.4.0 and slapd 2.4.15 . In my samba log appears this lines again and again: [2009/09/09 01:53:31, 0] lib/smbldap.c:smb_ldap_start_tls(600) Failed to issue the StartTLS instruction: Protocol error [2009/09/09 01:53:31, 1] lib/smbldap.c:another_ldap_try(1175) Connection to LDAP server failed for the 1 try! this means he cant connect to the LDAP Server because he want uses ssl, or? but i dont use ssl. I disabled it in openldap and also in smb.conf in my smb.conf i used: passdb backend = ldapsam:"ldap://127.0.0.1/" ldap ssl = Off so samba schouldn't use ssl, or? why is there this error message? in my slapd log i have this messages http://pastebin.jan500.org/234 the most import i think is: Sep 8 22:17:21 boss slapd[7532]: conn=0 op=0 do_extended: unsupported operation "1.3.6.1.4.1.1466.20037" Sep 8 22:17:21 boss slapd[7532]: send_ldap_result: conn=0 op=0 p=3 Sep 8 22:17:21 boss slapd[7532]: send_ldap_result: err=2 matched="" text="unsupported extended operation" Sep 8 22:17:21 boss slapd[7532]: send_ldap_response: msgid=1 tag=120 err=2 Sep 8 22:17:21 boss slapd[7532]: conn=0 op=0 RESULT tag=120 err=2 text=unsupported extended operation this comes because openldap dont use ldap, right? i hope you can helps me.. so long, Jan
