    Default SOLVED: LDAP error: - unable to get connection to server dummy_host:1

    Hey

    After desaster recovery I can not get LDAP up and running.

    Everything I could think of was being checked (I've replaced my hostname with xyz.ab)

    zmlocalconfig | grep ldap | grep url
    ldap_bind_url =
    ldap_master_url = ldap://xyz.ab:389
    ldap_url = ldap://xyz.ab:389
    telnet xyz.ab 389
    Trying 127.0.1.1...
    Connected to /xyz.ab.
    Escape character is '^]'.
    Any ideas where the "dummy_host:1" comes from?? What else can I check?

    This is solved.

    The complete error message was

    LdapException: com.zimbra.cs.ldap.LdapException: LDAP error: - unable to get connection: An error occurred while attempting to connect to server dummy_host:1: java.io.IOException: An error occurred while attempting to establish a connection to server dummy_host:1: org.newsclub.net.unix.AFUNIXSocketException: No such file or directory (socket: /opt/zimbra/openldap-2.4.33.4z/var/run/ldapi)
    and I also had a

    ldif_read_file: checksum error on "/opt/zimbra/data/ldap/config/cn=config/olcDatabase={0}config.ldif"

    I deleted the CRC comment inside the file and after a restart both errors were gone. Maybe someone needs that info some day ...

    The CRC warning is harmless. For whatever reason, openldap was not able to create the ldapi socket on your system when it was started the first time.
