Error when building a target that calls ldap_lts_inplace()

Question

I am writing a simple LDAP client that supports SSL/TLS using C in Xcode. I am using the following code snippet to start TLS:
ldap_start_tls_s(ld, NULL,  NULL); 
success = ldap_tls_inplace(ld); 
... etc
When I try to build, I get the following error:
Undefined symbols for architecture x86_64: 
"_ldap_tls_inplace", referenced from: 
      _auth_using_ldap in myLdapClient.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The function definition can be found in ldap.h, but I cannot build successfully.
How can I resolve this? Any helps or hints will be appreciated.
Current building environment:
- OS X 10.7.5
- Xcode 4.5.2
Linked libraries in Xcode:
- libldap.dylib
- Cocoa.framework
