Обсуждение: Doing an LDAP lookup from a SQL SELECT
I have an LDAP directory that contains contact information and a PostgreSQL table that has contact names. What I want to do is write a SELECT that will join the names in the table with the data in the LDAP directory (such as phone number, e-mail address, etc). Is this possible? Has anyone done this before? TNX in advance. David -- David R Robison Open Roads Consulting, Inc. 708 S.

Thanks, I found the extension but no documentation on how to install it or use it. Can you give me some pointers? TNX David

I copied the file to the "lib" directory under the PostgreSQL install and ran the SQL command:
CREATE FUNCTION ldap_search(text, text, text, text,text,text) RETURNS SETOF RECORD AS 'libdblink-ldap.dll', 'pg_ldap_search' LANGUAGE C STABLE;
it gave me the following error:
ERROR: incompatible library "C:/Program Files/PostgreSQL/8.2/lib/libdblink-ldap.dll": missing magic block
SQL state: XX000
Hint: Extension libraries are required to use the PG_MODULE_MAGIC macro.
any thoughts? TNX David

IIRC the binary release that's on there is too old to be supported on recent versions of PostgreSQL. You will need to build it from source, which should be patched with the magic block. //Magnus David R Robison wrote: > I copied the file to the "lib" directory under the PostgreSQL install > and ran the SQL command: > > CREATE FUNCTION ldap_search(text, text, text, text,text,text) RETURNS > SETOF RECORD AS 'libdblink-ldap.dll', 'pg_ldap_search' LANGUAGE C STABLE; > > it gave me the following error: > > ERROR: incompatible library "C:/Program > Files/PostgreSQL/8.2/lib/libdblink-ldap.dll": missing magic block > SQL state: XX000 > Hint: Extension libraries are required to use the PG_MODULE_MAGIC macro. > > any thoughts?

I cannot seem to create an environment to recompile the DLL. Does anyone have a compiled version of the DLL that is compatible with PostgreSQL 8.2 that they can share with me?
