Hello my fellow openldap friends,
I've installed openldap 2.4 on debian lenny usinf the Debian packages slapd and ldap-utils. For Authentification I would like to use sasl simple-bind but if I try e.g:
ldapsearch -D "cn=admin,dc=lug-saar,dc=spc" -W -d 255 respectively
ldapsearch -D "cn=Manager,dc=lug-saar,dc=de" -W -d 255
I got: ldap_sasl_interactive_bind_s: Invalid credentials (49)
As I couldn't find the Error using google yet, but getting as more confused
as more HOWTOS I read here is
Any HOWTOs you read were most likely wrong. Please list them for us so we can contact their authors and/or blacklist them on our FAQ. It's time we at least tried to put an end to the misinformation out there.
Read the OpenLDAP Admin Guide instead. Pay attention especially to the section on SASL Identities and mapping them to LDAP DNs.
SASL Binds do not use a DN in the Bind request, therefore you don't need the -D option (and anything you provide there is ignored by the server).
You specified "cn=Manager" above but in your slapd.conf below you defined "cn=root" for the rootdn. So even if you successfully told SASL which DN to use, you were telling it the wrong name. (Academic of course, given the other problems.)
You specified the rootpw twice, once in plaintext and once as an SSHA hash. The rootpw directive only accepts one value, and subsequent instances will simply replace prior ones. So your "rootpw secret" directive has no effect.
For SASL Binds based on passwords, slapd must have access to the plaintext of the password, so your SSHA hash will not work.
If you want to be able to SASL Bind to you your rootdn identity you're going to need to use an authz-regexp statement to map the SASL name to the proper DN.
