Описание (Description)
If the environment variable LDAPNOINIT is defined, all defaulting
       is disabled.
       The ldap.conf configuration file is used to set system-wide
       defaults to be applied when running ldap clients.
       Users may create an optional configuration file, ldaprc or
       .ldaprc, in their home directory which will be used to override
       the system-wide defaults file.  The file ldaprc in the current
       working directory is also used.
       Additional configuration files can be specified using the
       LDAPCONF and LDAPRC environment variables.  LDAPCONF may be set
       to the path of a configuration file.  This path can be absolute
       or relative to the current working directory.  The LDAPRC, if
       defined, should be the basename of a file in the current working
       directory or in the user's home directory.
       Environmental variables may also be used to augment the file
       based defaults.  The name of the variable is the option name with
       an added prefix of LDAP.  For example, to define BASE via the
       environment, set the variable LDAPBASE to the desired value.
       Some options are user-only.  Such options are ignored if present
       in the ldap.conf (or file specified by LDAPCONF).
       Thus the following files and variables are read, in order:
           variable     $LDAPNOINIT, and if that is not set:
           system file  ETCDIR/ldap.conf,
           user files   $HOME/ldaprc,  $HOME/.ldaprc,  ./ldaprc,
           system file  $LDAPCONF,
           user files   $HOME/$LDAPRC, $HOME/.$LDAPRC, ./$LDAPRC,
           variables    $LDAP<uppercase option name>.
       Settings late in the list override earlier ones.
