PcAnywhere Authentication problem

Hi

I just bought a copy of your product Symantec PcAnywhere 12,5 and I’m having some difficulties with it. On your website it says:

“Features removed in pcAnywhere 12.5:
Support for all authentication types except pcAnywhere, NT, and AD for Windows/PcAnywhere and Apple Open Directory for Mac/pcAnywhere and Linux PAM for Linux”

My question to you is if there is anyway for me to insert/connect a certificate to this version of PCA
