I have just installed Zimbra ( zcs-4.0.3_GA_407.UBUNTU6.tgz )on Ubuntu Edgy, worked like a charm but i dont have a license tab under "Global Settings" can someone shine a light on this topic it would be really great.
You don't have a license tab because you have the OSS edition, the license tab is only on the Network Edition.
If you intended to install the Network Edition then Ubuntu is not a supported platform, the NE is only supported on RHEL, OSX (intel and ppc) and SLES9.
