Subject: [PATCH] ipa-ca-install: print more specific errors when CA is already
aa60fb
 installed
aa60fb
aa60fb
This patch implements a more thorough checking for already installed CAs
aa60fb
during standalone CA installation using ipa-ca-install. The installer now
aa60fb
differentiates between CA that is already installed locally and CA installed
aa60fb
on one or more masters in topology and prints an appropriate error message.
