Installing wildcard certificate in a WLC (ver 7.0.240 and 7.5.102)

Is it possible to install a widcard certificate for web auth in those versions?
Is there any difference between this two versions.
Are both of them versions supporting wildcards certificates?
Here you have the log file resulting of installing the wildcart certificate in the wlc with v 7.0.240.
