Re: Get binary with JNDI - maybe OT

[Clayton Donley <clayton.donley@octetstring.com>]

In JNDI, you often need to add something to the environment you use to 
initialize the JNDI context in order to tell JNDI which attributes to 
treat as strings and which attributes are binary. This is very 
important since if you don't list a binary attribute in this 
environment variable and it is now a commonly known binary attribute 
(jpegPhoto for instance), you will likely get the value back in a 
corrupted or truncated way because JNDI will translate the bytes into 
UCS-2 encoded Java Strings.

Add something like:

env.put("java.naming.ldap.attributes.binary", 
"binattr1,binattr2,binattr3");
