Description

Using ldap-api to search an object using a binary value.
Using ldap filter syntax wich represent this binary value using escape sequence syntax.
Filter is ok when I'm using ldapsearch.

Getting a java exception:
LdapNetworkConnection WARN - org.apache.directory.shared.ldap.codec.api.MessageEncoderException: ERR_00004_PDU_BUFFER_SIZE_TOO_SMALL The PDU buffer size is too small !
org.apache.mina.filter.codec.ProtocolEncoderException: org.apache.directory.shared.ldap.codec.api.MessageEncoderException: ERR_00004_PDU_BUFFER_SIZE_TOO_SMALL The PDU buffer size is too small !

Here is my JUnit test to reproduce this issue:
public void testSimpleEscapedString() {
LdapConnection ldapCon = connectAd(true);

try {
// Real value \01\a1\52\44\9e\19\23\40\a3\05\08\0e\11\1c\17\e3 - ok with ldapsearch, exception with ldap-api
EntryCursor result = ldapCon.search("CN=Users,DC=myDomain,DC=loc",
"(objectGUID=
af)", SearchScope.SUBTREE, "objectsid",
"objectguid");

int count = 0;
while (result.next())

{ count++; Entry entry = result.get(); System.out.println(entry.getDn()); }

System.out.println(count + " entries found !");
} catch (Exception e)

{ e.printStackTrace(); fail("Test thrown an exception"); }

}
