问题
I am trying to use ldapsearch over ssl/tls connection, but it doesn't work:
ldapsearch -ZZ -d 5 -b "cn=Users,dc=my,dc=server,dc=com" -s sub -D
"cn=mydevice,cn=Users,dc=my,dc=server,dc=com" -h my.server.com -p 3269
-w "mypass" -x "(cn=test)"

ldap_start_tls: Can't contact LDAP server (-1)
The error message doesn't give enought hint on what is wrong. In contrast, a simple binding and search goes well without any problem on port 389.
Any hint?
P.S. Here is my ldap.conf:
TLS_REQCERT demand
TLS_CACERT ./cacert.pem
I have even tried to change TLS_REQCERT to never, but it still doesn't work. :-(
回答1:
First, replace -h my.server.com -p 3269 with -H ldaps://my.server.com:3269 as suggested by @dearlbry.
Then, in /etc/openldap/ldap.conf (or /etc/ldap/ldap.conf on my Ubuntu 13.04), disable certificate verification by adding this :
HOST my.server.com
PORT 3269
TLS_REQCERT ALLOW
You can also create a ldaprc file in the current directory with the same content if you don't want to affect the whole system.
This will enable ldapsearch over SSL, but without verification. Follow these steps to add certificate validation to the mix.
