Import user photo from LDAP into S-N (reloaded)

Dear Community,
my company is now changing to Service-Now and I'm currently working on adapting it to our needs. I worked the entire day long on the import of the LDAP user photo into S-N and I really got to thank john.roberts who first published in 2009 the base-script for what I need, see this topic: Importing user picture from LDAP into S-N.

Unfortunately his script is out-of-date as calling packages directly is now prohibited with the Calgary release and also his script is not able to update existing photos in S-N. So I accepted the challenge and modified his script.
It's already working and I want to share it with you in a minute, but maybe you guys can help me on a few questions as I'm new to S-N and JavaScript (previously I was more working on MS.NET).

Let's start withe the requirements:


1. Only import JPEG pictures into your LDAP, else you need to modify the script (to be honest I don't know if LDAP supports other formats)

2. Make sure to add the value "thumbnailphoto" to the system property "glide.ldap.binary_attributes". This system property should already exist on the sys_properties.list, otherwise add it manually by following the instructions that can be found on the S-N wiki.

Note: john.roberts script was aiming for the "jpegphoto", you can also use such attribute but you need to change the previous mentioned system property and also the following script accordingly (simply replace each thumbnailphoto with jpegphoto).

3. Make sure to set the system property "com.glide.loader.verify_target_field_size" to true. By default it's false. Otherwise follow the instructions given on john.roberts script.

Now to the Script:


Go to your "LDAP user import" transform map and add a new onAfter transform script.

Sorry, I'm horrible in giving proper comments on scripts. Please refer to john.roberts base-script or simply ask me if you have a question.


//add user image from ldap thumbnailphoto attribute and keep records in SN up-to-date

//**first check and get the existing photo of the SN-record
//this is vital if we want to update the photo when it has been changed in LDAP
//however the more users there are and the bigger the stored pictures are, it might slowdown the import process
//It can be simplified but then SN-pictures will not be removed automatically when the picture has been removed in LDAP
var existingPhoto = new GlideRecord('sys_attachment');
existingPhoto.addQuery('table_name','ZZ_YYsys_user');
existingPhoto.addQuery('table_sys_id',target.sys_id);
existingPhoto.addQuery('file_name','photo');
existingPhoto.query();

//**check if there is a picture on LDAP
if (source.u_thumbnailphoto != '') {
//**if there is no picture for the record in SN
if (!existingPhoto.next()) {
//**launch the function to attach the picture
attachPhoto();
}
//**if there is a picture for the record in SN
else {
var sysEncodedAttachment = new GlideSysAttachment();
var binData = sysEncodedAttachment.getBytes(existingPhoto);
var EncodedBytes = GlideStringUtil.base64Encode(binData);
//**verify if the current existing SN-picture for the record does not match the current LDAP picture
//if it does not match, delete the current SN-picture and launch the funtion to attach the new picture
if (EncodedBytes != source.u_thumbnailphoto) {
existingPhoto.deleteRecord();
attachPhoto();
}
}
}
//**if there is no picture on LDAP
else {
//**check if there is one on the SN-record and delete it
if (existingPhoto.next()) {
existingPhoto.deleteRecord();
}
}

//function to attach a new photo from the LDAP to the SN-record
function attachPhoto(){
var sysDecodedAttachment = new GlideSysAttachment();
var DecodedBytes = GlideStringUtil.base64DecodeAsBytes(source.u_thumbnailphoto);
var attID = sysDecodedAttachment.write(target, 'photo', 'image/jpeg', DecodedBytes);
var newAttachment = new GlideRecord("sys_attachment");
newAttachment.addQuery("sys_id", attID);
newAttachment.query();
if (newAttachment.next()) {
newAttachment.table_name = "ZZ_YYsys_user";
newAttachment.table_sys_id = target.sys_id;
newAttachment.content_type = 'image/jpeg';
newAttachment.update();
}
}


So... as you can see in order to be able to delete the photo on S-N if it has been removed in LDAP, I need to load the entire S-N image-data for each user-record there is. Meaning the more users you have and the bigger the stored pictures are, the longer it will take to verify and import. If you guys have an idea how to optimise this, I'd be grateful! Otherwise we can simplify the script, but then the photo on S-N will not be removed if it has been removed in LDAP, however it will still be able to update changes.

As john.roberts also suggested, you can afterwards test the script only on a specific user by adding to the LDAP filter (sAMAccountName=DesiredUsername*)

P.S.: Unfortunately S-N has not yet the possibility to directly import the LDAP photo, this is the only possibility we have

Hi Bryce.



Are you using a MID-server? If you are you need to add the property:


Name : glide.ldap.binary_attributes


Value : thumbnailPhoto


MID-server : <your midserver>


To the Properties of the midservers (requires restart of MID-server affected)


ecc_agent_property.list is the table you're looking for.



If you are running a version earlier then Fuji you might need to add it manually to the ../agent/properties/glide.properties file on the host hosting the midserver.


You are correct, not long after I posted I found the mention of the property to set for the mid-server and got it happy. Thank you!

Done some digging... or well googeling blindly trying to refine my search terms to get a useful hit.




I found this http://stackoverflow.com/questions/1040868/java-syntax-and-meaning-behind-b1ef9157-binary-address/ , which states the following:


The [ means array.


The B means byte.


The @ separates the type from the ID.


The hex digits are an object ID or hashcode.




So im guessing everything is fine...the value could change since its the id of the array (or am i misinterpretation it?).


But I don't get the value for the array, only the array number it self. I changed the photo-field of the user to a string-field and i can see that its populated with the different [B@1111111-values nothing else.




Since it seems to be working for everyone else Im thinking of charset. We are in sweden so we use åäö í…í„í– (if you can se them). I tried adding "charset=UTF-8" on the properties field for the data source of the ldap connection, but it made no difference.




What am i missing… what mistake have i made?


Does anyone have any suggestions with the "new" information?

Hello



We are also facing similar problem as Jonas. We setup everything as per ServiceNow Eilite and getting [B@ Strings in the import. However, when image is attached to the user in the Photo field after transform, there is no image.



Look forward to suggestions on this.



Thanks


Pranav, did you solve your problem?
