The type of each argument that you pass to execv may be correct, but paths[pathindex] is a path to a directory where execv expects a path to an executable.
For additional feedback, if execv returns -1, you can check the value of errno.

Net::LDAP::Control::PostRead(3pm) User Contributed Perl Documentation Net::LDAP::Control::PostRead(3pm)
NAME
Net::LDAP::Control::PostRead - LDAPv3 Post-Read control object
SYNOPSIS
use Net::LDAP;
use Net::LDAP::Control::PostRead;
use Net::LDAP::Constant qw( LDAP_CONTROL_POSTREAD LDAP_SUCCESS );
$ldap = Net::LDAP->new( "ldap.mydomain.eg" );
$postread = Net::LDAP::Control::PostRead->new( attrs => [ qw/givenName/ ] );
my $mesg = $ldap->modify( "cn=Barbara Jensen, o=University of Michigan, c=US",
replace => { givenName => "Babs" },
control => $postread );
if ($mesg->code eq LDAP_SUCCESS) {
my ($afterwards) = $mesg->control( LDAP_CONTROL_PREREAD );
my $entry = $afterwards ? $afterwards->entry() : undef;
if ($entry) {
print "givenName changed to '" .
join("', '", $entry->get_value(givenName") .
"' to 'Babs'
");
}
}
DESCRIPTION
"Net::LDAP::Control::PostRead" provides an interface for the creation and manipulation of objects that represent the "Post-Read Controls"
as described by RFC 4527.
In modification operations, the "Post-Read request control" indicates to the server that a copy of the modified entry after the update is
to be returned. After the successful completion of the operation, the accompanying "Post-Read response control" allows one to retrieve the
updated value from the servers's response.
One use case of this control may be to obtain values of operational attributes, such as the "entryUUID" and "modifyTimestamp" attributes,
updated by the server as part of the update operation.
CONSTRUCTOR ARGUMENTS
In addition to the constructor arguments described in Net::LDAP::Control the following are provided.
attrs => [ ATTR, ... ]
A list of attributes to be returned in the entry returned in the response control.
If absent, all attributes are returned.
Operational attributes may be included in the list by explicitly asking for them or by using special "+" feature (provided the server
supports this feature).
METHODS
As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the
current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument.
In addition to these methods, the control also supports the following method:
entry ()
Returns the entry from the response control in the response message to the LDAP request that contained the request control.
The result is either a Net::LDAP::Entry object or undefined.
