Why is ldapsearch so weird?

Question

bash

#! /bin/bash

ldapurl="ldap://ad.local.lan:389"
basedn="OU=some,DC=local,DC=lan"
binddn="CN=someuser,OU=piter,DC=local,DC=lan"
ldappas="somepass"

ldapsrc="ldapsearch -LLL -H \"$ldapurl\" -b \"$basedn\" -D \"$binddn\" -w \"$ldappas\""
$ldapsrc

Output:
Could not parse LDAP URI(s)="ldap://ad.local.lan:389" (3)

Moreover, if you write

echo $ldapsrc

and manually execute what echo returns - everything is fine.

Answer 1

You don't use spaces in any of your variables, so you don't need the inner quotes.

ldapsrc="ldapsearch -LLL -H $ldapurl -b $basedn -D $binddn -w $ldappas"
$ldapsrc

Answer 2

Try single quotes
ldapsrc='ldapsearch -LLL -H \"$ldapurl\" -b \"$basedn\" -D \"$binddn\" -w \"$ldappas\"'

Answer 3

and escape slashes in ldap://ad.local.lan:389
