codesniffer using pear standard ignore line indent

Question

using codesniffer with pear standard. I got over 20tsd errors cause of line indents. I use tab-stops for indenting. I try to disable that check but I failed.

I removed the last rule from the generic standards in the ruleset.xml for the pear standard. Yet the indenting is still considered an error.

How do I remove the indention checks completely for the pear standard?
