[Koha] LDAP authentication

[Vitor Fernandes]

Hi there.

I want to use LDAP authentication on my Koha (3.2.2).
There is any tutorial to do this?

Now I've added this block to my koha-conf.xml:

<useldapserver>1</useldapserver>
<ldapserver id="ldapserver" listenref="ldapserver">
<hostname>*******</hostname>
<base>*********</base>
<user>*******</user>
<pass>*******</pass>
<replicate>0</replicate>
<update>0</update>
<auth_by_bind>1</auth_by_bind>
<mapping>
        <firstname is="givenName" ></firstname>
        <surname is="sn" ></surname>
        <userid is="userPrincipalName"></userid>
        <email is="mail"></email>
</mapping>
</ldapserver>

I don't want to replicate neither update users in Koha. LDAP will be
only used to authentication.
But i'm having this error: "Can't call method "bind" on an undefined
value at /usr/share/koha/lib/C4/Auth_with_ldap.pm line 122".
The hostname of LDAP is correct... I've checked Auth_with_ldap.pm and
the problem is that $db variable (Net::LDAP->new(hostname)) is empty.

Any solution?

Thanks for your time.
Regards.
