Hello Giuseppe, Thank you for your reply. After obtaining more information from our network personnel and a little trial and error, I was able to get the pg_hba.conf file edited correctly specifying ldap authentication against our Active Directory domain and users can now connect. Your second example was very close to what I needed.

I found the documentation on the web site quite good. These are two examples I use every day for authenticating postgres users to a remote AD: host neos all 127.0.0.1/32 ldap ldapserver=ipaddress ldapbasedn="OU=xxx,DC=yyy,DC=local" ldapbinddn="CN=uuu,OU=xxx,DC=yyy,DC=local" ldapbindpasswd=password ldapsearchattribute=sAMAccountName host neos all 10.42.112.0/24 ldap ldapserver=ipaddress ldapprefix="cn=" ldapsuffix=", ou=Users, ou=xxxx, dc=yyy, dc=local" The first uses a special account for connecting and looking for sAMAccountName before checking credentials, the second one connect directly with specified credentials. Please note, that beside importing all databases, you should also import "globals" that contains all role definitions. More info, for postgres 9.3, on the web site http://www.postgresql.org/docs/9.3/interactive/auth-methods.html#AUTH-LDAP More info about moving globals http://www.postgresql.org/docs/9.3/static/app-pg-dumpall.html Please note that postgresql connect to AD, it is not the other way around.
