Re: Antw: OpenLDAP slapd problems - ldap_result: Can't contact LDAP server (-1) --- Low Sensitivity/Aerospace Internal Use Only

Vikas, thanks for replying some more, but your last email is a little out of context for me personally. That i can understand, may be i have moved in more depth.

I did drop the -b argument (and the associated value) and still the slapd daemon crashed. I am starting to wonder if this is an OpenLDAP or LTB Project OpenLDAP problem since no one else is chiming in with solutions and troubleshooting.

As for the slaptest, it didn't generate *any* content into the slapd.d directory at all. I mentioned this to the person I was collaborating with since I am attempting to document a process from scratch-to-finish.

That same person suggested I attempt to use ApacheDirectoryStudio to interact with the slapd and configurations. I just attempted to connect to the cn=config ??Context?? And I was able to add an attribute ( *olcTLSCipherSuite*), but as soon as I attempted to add a value ( *HIGH:MEDIUM+TLSv1+SSLv3*) the connection dropped in ApacheDirectoryStudio. *Warron French, MBA, SCSA* From: Vikas Parashar <para.vikas(a)gmail.com&gt; To: Warron S French <Warron.S.French(a)aero.org&gt;, Cc: Ulrich Windl <Ulrich.Windl(a)rz.uni-regensburg.de&gt;, openldap-technical(a)openldap.org Date: 01/27/2014 09:24 AM Subject: Re: Antw: OpenLDAP slapd problems - ldap_result: Can't contact LDAP server (-1) --- Low Sensitivity/Aerospace Internal Use Only ------------------------------ Hi, Sorry! that was the typo. -b for the base only. In ldap modify, you don't need to use -b. You can do the same thing with slapd.conf file. later on, you can create a slapd.d directory with the help of slaptest command. slaptest -f slapd.conf -F slapd.d In this temporary directory, you will get a configuration({0}config.ldif) file under slapd.d/cn=conifg directory. you can replace it and resxtart the service. Or in current ldapmodify, please run it with deeper debug level. You may use -d option for it.

And I don't know if it makes any difference, but I don't have TLS configurations in place yet; that is what I am attempting to accomplish.
