LDAP Add and Read Binary Data

Hello, my friends I tried to register binary data in a Directory using LDAP Functions of php 4.04. Thsese data are UTF8 encoded strings in our local language. These tries were not successful and php did not register data in Directory. I would want to know if php LDAP functions support binary data registration. How php supports binary data in its LDAP function. If the functions don\'t support binary data registration, which solution is advisable. Would we expect a new php version with this feature. Does a version exist with this feature in CVS, and is this version reliable. Thank you very much Antonis
