Unable to get local issuer certificate? Is the adcacert.asc file the actual CA cert in ascii/pem/base64 format from the AD CA? Do you have more than one CA or subordinate CAs? If so, you may need to have the entire CA cert chain in the file.


If you are sure that adcacert.asc is from the AD CA, then try adding TLS_CACERT /path/to/adcacert.asc to your ~/.ldaprc file and try the above ldapsearch again.

Let's see what the subject and issuer are in the CA cert:

        Rich,

        Status: [81  - LDAP error: Can't contact LDAP server]

        I have imported right CA to IPA box and the out put is:
Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI CA certificate CTu,u,Cu
        Imported CA                                                  CT,,C
        Server-Cert                                                  u,u,u
         And also I done the openssl s_client option too, but no luck.

    What exactly did you do? with openssl s_client?

    Did you try
    /usr/lib64/mozldap/ldapsearch -h fqdn.of.ad.hostname -Z -P
    /etc/dirsrv/slapd-YOURINSTANCE/cert8.db -s base -b "" "objectclass=*"

    LDAPTLS_CACERT=/path/to/adcacert.asc ldapsearch -d 1 -x -h
    fqdn.of.ad.hostname -p 389 -Z -s base -b ""

        Without cert when I try ldap search its gives out put. but
        with cert (AD CA) through error.
         Please help me fix this issue.
