Recently I tried to configure my computer to mount an NFS share (more or less without success). One of the steps was to install a pem-certificate from my employer for use with ldaps requests. In order to get it work I tried different things, like running the c_rehash command for installing the certificate system-wide. Now, since this time Otter tells me at each https site that the owner of ... has configured their page improperly, which is not true. Firefox does not complain on these pages. Is there any idea how to undo this? Yes, this is a classical case of root not knowing what he does.
