OpenLDAP also implicitly terminates every access directive with this rule whether present or not to close any remaining doors - anything not covered by a preceding clause can do nothing. Given only this access directive or no access directive which defaults to this one only the rootdn superuser and its rootpw could be used to write to the DIT.
Expressions may be combined using the following operators, listed in decreasing order of precedence: This may be used to override the normal precedence of operators.
Conditional ConstructsUp: When commands are grouped, redirections may be applied to the entire command list. For example, the output of all the commands in the list may be redirected to a single stream.
Since the list is executed in a subshell, variable assignments do not remain in effect after the subshell completes. No subshell is created. The semicolon or newline following list is required.
In addition to the creation of a subshell, there is a subtle difference between these two constructs due to historical reasons. The braces are reserved words, so they must be separated from the list by blanks or other shell metacharacters.
The parentheses are operators, and are recognized as separate tokens by the shell even if they are not separated from the list by whitespace.
The exit status of both of these constructs is the exit status of list.
GNU ParallelPrevious: Compound CommandsUp: The format for a coprocess is: NAME must not be supplied if command is a simple command see Simple Commands ; otherwise, it is interpreted as the first word of the simple command. When the coprocess is executed, the shell creates an array variable see Arrays named NAME in the context of the executing shell.
The standard output of command is connected via a pipe to a file descriptor in the executing shell, and that file descriptor is assigned to NAME. The standard input of command is connected via a pipe to a file descriptor in the executing shell, and that file descriptor is assigned to NAME.
This pipe is established before any redirections specified by the command see Redirections. The file descriptors can be utilized as arguments to shell commands and redirections using standard word expansions. The file descriptors are not available in subshells. The wait builtin command may be used to wait for the coprocess to terminate.
Since the coprocess is created as an asynchronous command, the coproc command always returns success. The return status of a coprocess is the exit status of command.
GNU Parallel is a tool to do just that. GNU Parallel, as its name suggests, can be used to build and run commands in parallel.
You may run the same command with different arguments, whether they are filenames, usernames, hostnames, or lines read from files. GNU Parallel provides shorthand references to many of the most common operations input lines, various portions of the input line, different ways to specify the input source, and so on.
Parallel can replace xargs or feed commands from its input sources to several different instances of Bash. For a complete description, refer to the GNU Parallel documentation. A few examples should provide a brief introduction to its use.
For example, it is easy to replace xargs to gzip all html files in the current directory and its subdirectories: You can use Parallel to move files from the current directory when the number of files is too large to process with one mv invocation: While using ls will work in most instances, it is not sufficient to deal with all filenames.
If you need to accommodate special characters in filenames, you can use find. This will run as many mv commands as there are files in the current directory. You can emulate a parallel xargs by adding the -X option:Warning re Databases Created or Restored under Firebird All users upgrading from Firebird to a higher sub-release are strongly advised to migrate databases using gbak backup/restore.
If this is impracticable, at least rebuild all compound indices in the databases being migrated. Chapter 6. LDAP Configuration.
This chapter describes, in mind-numbing detail, all parameters and attributes/directives used to control the LDAP systems covered in this Guide (well, eventually it will). Specifically OpenLDAP's OLC (cn=config) and grupobittia.com (Server configuration), OpenLDAP's grupobittia.com (Client and some Server configuration) and ApacheDS configuration (grupobittia.com).
1. Introduction to OpenLDAP Directory Services. This document describes how to build, configure, and operate OpenLDAP Software to provide directory services.
This includes details on how to configure and run the Standalone LDAP Daemon, slapd(8). It is intended for new and experienced administrators alike.

Attempt to write a read-only database attempt to write a readonly database Description: An unhandled exception occurred during the execution of the current web request. A customer asked that we check out his intranet site, which was used by the company's employees and customers.
This was part of a larger security review, and though we'd not actually used SQL injection to penetrate a network before, we were pretty familiar with the general concepts.
