Samba share not working for osx users, but fine for windows users

Using webmin on a linux box I setup a few samba shares. I can access them fine using any windows machine, but when I connect to the server using osx, finder prompts me for a username and password then tells me no dice. Is there something specific that needs to be setup for osx to access a share vs windows?

NOTE:
After I enter my credentials it shows me the shares, but when I select any of them it then give me a general error connecting to server message.

My smb.conf is as follows:

[global]
    log file = /var/log/samba/samba.log
    guest account = nobody
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
    add group script = /usr/sbin/groupadd '%g'
    admin users = root
    obey pam restrictions = yes
    delete group script = /usr/sbin/groupdel '%g'
    socket options = TCP_NODELAY
    add user to group script = /usr/sbin/usermod -G '%g' '%u'
    encrypt passwords = yes
    passdb backend = tdbsam
    passwd program = /usr/bin/passwd %u
    wins support = true
    dns proxy = no
    netbios name = FILESERVER
    server string = Company FileServer
    unix password sync = yes
    workgroup = OfficeWG
    os level = 20
    add user script = /usr/sbin/useradd -m '%u' -g users -G users
    auto services = global
    security = share
    syslog = 0
    panic action = /usr/share/samba/panic-action %d
    delete user script = /usr/sbin/userdel -r '%u'
    max log size = 1000
    pam password change = yes

[officemain]
    writeable = yes
    path = /mainstorage/officemain

[homes]
    browseable = no
    comment = Home Directory
    writeable = yes
    path = /mainstorage/home/%S

[markshome]
    browseable = no
    comment = Marks Home Folder
    writeable = yes
    path = /mainstorage/home/markepstien

I have cleared the samba log and tried to reconnect. Here are the contents of the log. I see it says incorrect password, but I can connect fine using the user/pass from a windows machine.
