If this is an exact cut and paste, you still have authentication issues. A leading space in slapd.conf lines can be used to continue previous directives if they can take multiple values such as the "access" directive can. In the above, you have "access to attrs=userPassword" as a subdirective of the previous "access" directive. Re-edit your config file and make it look like this: <div class="im"> include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema pidfile /usr/var/run/slapd.pid argsfile /usr/var/run/slapd.args access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to * by self write by users read by anonymous auth access to attrs=userPassword by anonymous auth by self write by * none TLSCACertificateFile /usr/var/openldap-data/cacert.pem TLSCertificateFile /usr/var/openldap-data/servercrt.pem TLSCertificateKeyFile /usr/var/openldap-data/serverkey.pem database bdb suffix "dc=test,dc=com" rootdn "cn=Manager,dc=test,dc=com" rootpw XXXX directory /usr/var/openldap-data/<a href="http://test.com/" target="_blank">test.com</a> index objectClass eq </div>I suspect that's where things are getting weird. Personally, I prefer to indent my access directives, so the above bit would look like: --------------------------------------- <div class="im"> access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to * by self write by users read by anonymous auth access to attrs=userPassword by anonymous auth by self write by * none </div>--------------------------------------- But that's just me. Unless you specify "-Z" to your ldapsearch command, TLS/SSL is not being used, so you're using simple SASL authentication...and again the passwords in the database MUST BE IN CLEARTEXT IF YOU USE SASL. Most Linux systems will use an MD5 encryption and that won't work with SASL. You might also want to try adding "-d 255" to the ldapsearch command. That will spit out lots of debug info that may help you sort out just exactly where the thing's dying. <div> <div></div> <div class="h5"> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> What you say?

It looks like error 49 is gone. </blockquote>Ok, if error 49 is gone, but you're not getting any data back, then user "nilesh" probably doesn't have read access to the database. If you have your slapd manual handy, read up on the "access" directives. If you want a user to see any and all of their info, then you need a directive such as: access to * by self read by * none in slapd.conf. That permits someone to read their own data. If you want to let them modify their data: access to * by self write by * none (note that "write" permission also includes all lower permissions such as auth, read, search, etc.) What else I need to do to fix this issue. Looks like you're authenticating fine now, but you have to set up access rules to allow users to see things. Here's a good on-line reference book on how to manage an LDAP server: <a href="http://www.zytrax.dom/books/ldap" target="_blank">http://www.zytrax.dom/books/ldap</a> Also, the OpenLDAP System Admin Guide should have been placed in /usr/share/doc/openldap-servers-version/guide.html (replace "version" with the appropriate version number) when you installed the OpenLDAP server RPM. You can view it by opening a browser and going to file:///usr/share/doc/opeenldap-servers-version/guide.html <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Thanks and Regards, -Nilesh On Fri, Aug 14, 2009 at 10:04 AM, Rick Stevens <<a href="mailto:ricks@nerd.com" target="_blank">ricks@nerd.com</a>> wrote: Nilesh Joshi wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Thanks Rick. <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">I have checked using -w password.

Error 49 is "invalid credentials," meaning that you didn't hand the </blockquote>ldapsearch the right password for the user you're trying to bind as. Try it again, but rather than using the "-W" (interactive) flag, try: -w 'your-password-here' If the password has shell metacharacters in it, they may be being interpreted by the shell before being handed to the ldapsearch command. Using the -w and the password enclosed in single quotes prevents that. You also have to make sure that the user you're trying to bind as has access to the userPassword attribute in the slapd.conf file: access to attrs=userPassword by anonymous auth by self write by * none ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer <a href="mailto:ricks@nerd.com" target="_blank">ricks@nerd.com</a> - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - I never drink water because of the disgusting things that fish do - - in it. - - -- WC.
