Hi, | ||
|
||
This is 'eldap', the Erlang LDAP library. | ||
|
||
It exports an API that can do all possible operations | ||
you may want to do against an LDAP server. The code has | ||
been tested to work at some point, but only the bind | ||
and search operations are running daily in our products, | ||
so there may be bugs lurking in some parts of the code. | ||
|
||
To just use eldap for doing authentication, do like in: | ||
|
||
{ok,X} = eldap:open(["ldap.mycorp.com"], []). | ||
eldap:simple_bind(X, "uid=tobbe,ou=People,dc=mycorp,dc=com", "passwd"). | ||
|
||
In the doc/README.example you'll find a trace from a | ||
Erlang shell session as an example on how to setup a | ||
connection, authenticate (bind) and perform a search. | ||
Note that by using the option {ssl, true}, you should | ||
be able to setup an SSL tunnel (LDAPS) if your Erlang | ||
system has been configured with SSL. | ||
|
||
In the test directory there are some hints and examples | ||
on how to test the code and how to setup and populate | ||
an OpenLDAP server. The 'eldap' code has been tested | ||
agains OpenLDAP, IPlanet and ActiveDirectory servers. | ||
|
||
If you plan to incorporate this code into your system | ||
I suggest that you build a server/supervisor harnesk | ||
that uses 'eldap' (as we have done in our products). | ||
|
||
Good luck ! | ||
/Tobbe |
