Re: Bind using a user other than organizationalRole user

Hello all,

Thank you for the insights.
In general: if you haven't explicitly defined an ACL, OpenLDAP is
configured to allow anonymous reads -- this is *not* sufficient to auth.
You will want to allow anonymous auth to the appropriate DNs.
Yeah, I figured that out. I probably created a situation where:
 1) I tried authenticating without the proper ACL, it failed;
 2) Entered trial and error mode, tried changing userPassword to {CLEARTEXT}secret_12345
 3) Didn't work either;
 4) Put the: "access to * by * read" ACL, restarted server.
 5) Tried authenticating with secret_12345, didn't work
 6) Too much time spent, couldn't spend more time on the issue. Tried just converting secret_12345 to SHA-1 and updating the value of userPassword
 7) Worked!
 8) Could finally relax and get out to get some fresh air ;)

So, the point is, I could get it to work. This is not to say I wouldn't like to know what happened, it is on my list, I might go through the process again next weekend and document my findings, but I think you guys already said what was to be said about the issue.

Cheers and peace!

There's nothing wrong with storing a clear-text password like

userPassword: secret_12345

in the directory entry. In fact you have to when e.g. using SASL/DIGEST-MD5
bind with in-directory passwords.

When processing a simple bind slapd looks whether a password is stored in
hashed form by looking at a magic prefix like {SSHA}. If that prefix is not
there it is assumed that the password is stored in clear and this gets compared.

Hmm, I think you mixed up something.

Ciao, Michael.
