Pidgin and Sametime Server - extst.ibm.com

Nice, I was able to connect to IBM's Sametime server "extst.ibm.com" with Pidgin with this little trick.

I used to get this error "Client version mismatch" or "Unable to connect: Error resolving lotus.sametime.com: 11001"

On path: %appdata%/.purple/

A solution on the client side list to fake the version in accounts.xml.
Insert/change the lines (described here https://developer.pidgin.im/ticket/12623 ) in the section of Sametime account in accounts.xml.

BleedYellow: im.bleedyellow.com and IBM SmartCloud (Lotus Live) (im.na.collabserv.com) worked by only setting "Hide client identity"
