Dear Team,

I have McAfee Web Gateway proxy, for Mac mini users i am deploying Kerberos authentication on it for other windows machines NTLM is there. After creation of a kerberos user on AD and keytab generation and the keytab file also uploaded in the web gateway.

The main issue is the Mac mini is not able to authenticate user groups for internet access and throws an error "you must be authenticate to access this URL." . I using FQDN of web gateway inthe proxy settings but as per the packet capture for mac mini there is not request for " TCP.PORT==88 || UDP.PORT==88". please suggest what settings required on mac for this issue.

Thanks & Regards
