- Is it possible, to login to it via Single Sign On? Does
anybody know an Extension for this?
It depends on what you mean by single sign on. If you mean LDAP, Smart Cards, or NTLM, then yes; if you mean Kerberos, I don't think so, but I've never really looked particuarly for that. You can check the extension categories on meta and on mediawiki.org for any of the above.
