Access OS X file share from Ubuntu

I've been struggling with this for a while and I'm hoping somebody here has an answer. I have a Mac OS Server with file sharing turned on and everything as wide open as I can make it (777 permissions, guest access allowed, all protocols open). I can see the server from my ubuntu installation and when I click on it I'm asked for a username and password but there is no combination (valid user on either machine, empty username and password, admin accounts, default username and password, random junk) that lets me access the share. Other macs have no issues accessing it and, weirdly, multiple Windows 2000 computers have no issues accessing this share.

I've searched and searched and tried every configuration I can find but I can't figure out how to access this share from my ubuntu machine. Any ideas?

You don't make it clear whether you are trying to use AFP or SMB to access the Mac server.

If AFP then Ubuntu would need to use an open-source package called Netatalk. It would be important to have a recent version of Netatalk so as to be compatible with Apple's implementation as Apple have made changes over time.

If using SMB then with El Capitan Apple have recently implemented a new change intended to enhance security. This involved signing all the network packets. Some SMB clients cannot cope with this feature although I would expect a Linux machine running a recent version of SAMBA4 to be able to. It may require enabling a matching option in SAMBA. It is however possible to turn this feature off on the Mac server by doing the following.

sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server SigningRequired false

A final possibility is that the Mac server could be setup to use SSL encryption for AFP and/or SMB. If a self-signed rootCA certificate have been used this would require the clients e.g. Ubuntu to have a copy installed and trusted.
