Description

I created a user with the following ldif:

dn: cn=dgoetz,ou=users,dc=localdomain
objectClass: inetOrgPerson
cn: dgoetz
sn: Goetz
description: Dirk Goetz
userPassword: {SSHA}SmI4N/QECJfMFprv9sMnTD7KZUq46Yw8
givenName: Dirk
mail: dgoetz@localdomain
uid: dgoetz
jpegPhoto:< file:///root/dgoetz.jpg

When I login with the user the avatar is downloaded and the file is created but is not a valid picture.

# file /var/lib/foreman/public/assets/avatars/6e15a0e85405ddd9f25abc3aee0b212ea2ca6bfb.jpg 
/var/lib/foreman/public/assets/avatars/6e15a0e85405ddd9f25abc3aee0b212ea2ca6bfb.jpg: data

If I search the ldap I get:

# dgoetz, users, localdomain
dn: cn=dgoetz,ou=users,dc=localdomain
objectClass: inetOrgPerson
cn: dgoetz

And if I copy the base64 string to a file, join the lines and decode it, I get a valid jpeg back.

# cat /tmp/base64 | base64 -d > /tmp/dgoetz.jpg
# file /tmp/dgoetz.jpg 
/tmp/dgoetz.jpg: JPEG image data, JFIF standard 1.01

So something seems to be broken, but looking in the code I have no idea what. When I tried to remove the decoding and output the file in binary I already got some content not maching the base64 string and if output was not written binary I got an empty file. Also removing the to_utf8 for testing showed the same result.

I'm seeing this issue too, the avatars obtained from our Active Directory are not being saved correctly:

$ od -c /var/lib/foreman/public/assets/avatars/54cf8135e2114eb915bcbfaf162f324eeab26293.jpg [18:14:38]

0000013

There is also another issue, as when the Foreman pages try to download the avatar image they get a 404:

foreman-ssl_access_ssl.log:10.4.4.48 - - [22/Apr/2017:18:12:44 +0100] "GET /images/avatars/54cf8135e2114eb915bcbfaf162f324eeab26293.jpg HTTP/1.1" 404 1564 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36"

This is with Foreman 1.14.3/Katello 3.3.1

Hi
foreman-1.15.0 contains the same bug. I tried a little bit to find out what happen.
My fix is this:
Edit in this file: /usr/share/foreman/app/models/auth_sources/auth_source_ldap.rb like this:
def store_avatar(avatar)
#avatar = avatar.to_utf8
avatar_hash = Digest::SHA1.hexdigest(avatar)
avatar_file = "#{avatar_path}/#{avatar_hash}.jpg"
unless FileTest.exist? avatar_file
FileUtils.mkdir_p(avatar_path)
#File.open(avatar_file, 'wb') { |f| f.write(Base64.decode64(avatar)) }
File.open(avatar_file, 'wb') { |f| f.write(avatar) }
end
avatar_hash
end

Maybe you have to add one more symbolic-link here: /var/lib/foreman/public/images -> assets.
Keep sure, to set the owner and group to foreman:foreman.

Restart foreman and httpd and it will give you the avatar picture back.

I can confirm the mentioned fix works.

For the code change I could create a pull request, but I have no idea where the symlink has to be created or if it would be better to change the URL instead (where I could not find the origin of).

Updated by Derek Wright about 6 years ago

Did some testing on this and the issue appears to be that net/ldap will automatically convert the base64 data to binary representation (Net::BER::BerIdentifiedString). We can check the type by doing the following in app/models/auth_sources/auth_source_ldap.rb(line 218):

avatar = avatar.instance_of?(Net::BER::BerIdentifiedString) ? avatar : avatar.to_utf8

Now, where I'm getting hung up is how we want to handle writing the data, I don't want to move the base64 decode up sooner in the logic as it will increase overhead on every login. There is also the possibility to maybe use MimeMagic and detect the current filetype and if its not image/jpeg, overwrite the file (this will also have a small performance penalty). Looking for some thoughts on how best to implement that part from the Devs.

app/models/auth_sources/auth_source_ldap.rb(line 224):

      File.open(avatar_file, 'wb') { |f| f.write(Base64.decode64(avatar)) } # This base64 will only need to be done if its NOT instance_of Net::BER::BerIdentifiedString
