node-ldapjs | LDAP Client and Server API for node.js | Identity Management library

I have a NodeJS / Express RESTful API that proxies requests from an Active Directory LDAP Server. I do this because LDAP queries tend to be slow. I use the RESTful API to cache and refresh data intermittently. I recently attempted to add the thumbnail photo. In research it appears the library that I am using ldapjs is converting the native ldap byte array to a string.

Example of what this looks like:

\ufffd\ufffd\ufffd\ufffd\u0000\u0010JFIF\u0000\u0001\u0000\u0001\u0000x\u0000x\u0000\u0000\ufffd\ufffd\u0000\u001fLEAD Technologies Inc. V1.01\u0000\ufffd\ufffd\u0000\ufffd\u0000\u0005\u0005\u0005\b\

Due to this fact the image does not render correctly on the angular client app. So based on my research, here are some attempts in correcting this problem:

• Convert the string to a byte array using different methods (See code examples)

• Modify the ldapjs library to render the data as a byte array in the RESTFUL as in the following, then bind the byte stream to the angular page:

I first want to mention that I'm not an expert with LDAP.

What I need is to get from my company's ldap some information including the user photo. My problem is that after I get all the information I need, the thumbnailPhoto appears to be somehow corrupted. I'll show an example: \ufffdPNG\r\n\u001a\n\u0000\u0000\u0000\rIHDR\u0000\u0000\u0000\ufffd\u0000\u0000\u0000\u ...

I first noticed this when I tried to apply it on my front end client and couldn't make an image from the returning Buffer. Plus when I checked in LDAP to see the photo size of the returned one is almost double in size.

I checked to see if there was a problem with way the photo was saved in LDAP, copy pasted into a converter and all was fine.

I'll give a code snippet of how I get info from LDAP with a library called activedirectory:

I'm trying to get information from AD using node.js. I've tried activedirectory and ldapauth-fork and in general the code works, but if I need some octetstring data like objectGUID, I see a rubbish string in the object. I found that binary data is converted into a string as utf-8. But the problem is that the data is damaged during convertion (a lot of cahrs with 65533 code) and I can't revert the string to original binary.

How can I access data in octetstring format to get correct binary representation?

I have LDAP connections working properly with node-ldapjs. I am trying to implement LDAPS connections with node-ldapjs. The setup/configuration I am using is equivalent to the solution which was described as being successful by another individual and was posted here - https://github.com/mcavage/node-ldapjs/issues/307. My code is shown below. When I execute the code below, I get the following message:

{[Error: unable to get local issuer certificate] code: 'UNABLE_TO_GET_ISSUER_CERT_LOCALLY'}

Here is the full stacktrace -
