2. 2 What is LDAP? ● Mature TCP/IP protocol ● Provides directory access ● Standardized in RFC 4510 ● In most Unix and Linux distros ● Also Blackberry, Android, Iphone

3. 3 What is LDAP?

4. 4 Typical use cases 1.Telephone directory 2.Corporate address book 3.Employee ID card directory 4.Password directory 5.Recipe collection?...Similar in utility to SQL

5. 5 Compare LDAP & SQL LPAP is... ● A protocol ● Tuned for read ● Widespread SQL is... ● A language ● Balanced R/W ● Transactions ● Consistency ● Other services

6. 6 Compare LDAP & SQL

7. 7 Mainstream use ● Novel SUSE Linux ● MS active directory ● Apple OS X addressbook ● Email address autocompletion ● Kontakt, Evolution, Thunderbird... ● IP hardphones and softphones ● Snom, Polycom, Cisco, Ekiga

8. 8 Implementations ● OpenLDAP (GPLv2) ● Mozilla C/Java ● Alcatel-Lucent ● Alot of others

9. 9 OpenLDAP helloworld #include int main(int argc, char *argv[]) { ldap_initialize(&ld, "ldaps://name.host.com:636/"); ldap_simple_bind_s(ld, "uid=me,ou=people,dc=host,dc=com", "pwd"); ldap_search_s(ld, "dc=intern,dc=host,dc=com", LDAP_SCOPE_SUBTREE, "(sn=Chambe-Eng)", NULL, 0, &result); dn = ldap_get_dn(ld, ldap_first_entry(ld, result)); printf("dn: %s\n", dn); ldap_memfree(dn); ldap_msgfree(result); ldap_unbind(ld); } $ cc -c helloldap.c && cc helloldap.o -lldap -llber &&./a.out dn: uid=Chambe- Eng,ou=no,ou=people,dc=intern,dc=host,dc=com
