It echos fine but does not run fine.

You have to run it in a script.

#---------
#!/bin/bash
variable="-b \"dc=example,dc=com\""
ldapsearch $variable
echo This is echoed: $variable
#----------

when you run sh -x to it this is the result.
+ variable=-b "dc=example,dc=com"
+ ldapsearch -b '"dc=example,dc=com"'
ldap_sasl_interactive_bind_s: Can't contact LDAP server
+ echo This is echoed: -b '"dc=example,dc=com"'
This is echoed: -b "dc=example,dc=com"


You will notice that is echos fine but when it is run it has the single quotes.
Ignore the ldap error this is just an example of how BASH add single quote when the command is run.

PPI::Token::Quote::Double(3pm)				User Contributed Perl Documentation			    PPI::Token::Quote::Double(3pm)

NAME
PPI::Token::Quote::Double - A standard "double quote" token INHERITANCE
PPI::Token::Quote::Double isa PPI::Token::Quote isa PPI::Token isa PPI::Element DESCRIPTION
A "PPI::Token::Quote::Double" object represents a double-quoted interpolating string. The string is treated as a single entity, PPI will not try to understand what is in the string during the parsing process. METHODS
There are several methods available for "PPI::Token::Quote::Double", beyond those provided by the parent PPI::Token::Quote, PPI::Token and PPI::Element classes. Got any ideas for methods? Submit a report to rt.cpan.org! interpolations The interpolations method checks to see if the double quote actually contains any interpolated variables. Returns true if the string contains interpolations, or false if not. simplify For various reasons, some people find themselves compelled to have their code in the simplest form possible. The "simply" method will turn a simple double-quoted string into the equivalent single-quoted string. If the double can be simplified, it will be modified in place and returned as a convenience, or returns false if the string cannot be simplified. SUPPORT
