  Closing due to inactivity. I'm assuming it works until proven wrong.

  Hi Jens,

Sure, I will test it tomorrow and I will be back with an answer.

  Hi Dragos,

Could you do me a favor and test the latest code from the Subversion repository? I have made changes to accommodate binary attributes if you declare them as binary attribute on the LDAP Schema tab:

  Hi Jens,

I have solved the problem, successfully write, read and delete jpegPhoto value in the LDAP. I had to write a hotfix that adds the modified version of two methods LDAPUserFolder. manage_setUserProperty and LDAPDelegate.modify. In both methods I have removed the code that encodes to utf8 the value to be saved in the LDAP. So:

1. to write: manage_setUserPropertyEx(user_dn=..., prop_name='jpegPhoto',
2. te delete: manage_setUserPropertyEx(user_dn=..., prop_name='jpegPhoto', prop_value=None)
3. to read I have this method:

security.declareProtected(view, 'getUserAvatar')
def getUserAvatar(self, name):
""" """
return self.getPhysicalRoot().acl_users.getUser(name).avatar

and in ZPT:

<img tal:attributes="src string:${site_url}/getUserAvatar?name=${...}" ... />

Hope this will help.

Thanks again,

  I honestly don't know. I never had the need to manipulate binary
fields such as jpegPhoto. I don't even know if this is possible using

  Hi Jens,

I am trying to modify the jpegPhoto field in the LDAP (upload a picture). I have succesfully read this property and it works perfect - the image display ok.

Basically I am calling the method manage_setUserProperty with prop_name='jpegPhoto' and the question is how to pass the prop_value. I have tried in different ways ( or base64.encodestring( and it doesn't work.

Could you please guide me on how to pass the correct value?

Thank you very much.
