Hi folks,
I'm having this same problem, and am am wondering if anyone has had any luck solving this within BBEdit? The command line tools are working just fine, but BBEdit always fails svn operations with "authorization failed". I can't find any information about svn authentication in the manual. I've tried creating new keys in Keychain Access that mirror the way BBEdit stores sftp authentication information to no effect. Finally, all discussion threads about this situation (which seems new to BBEdit 10) are unresolved. I'm trying the BBEdit trial, and will probably buy it even if I can't get SVN working, but it kinda sours the deal a bit to have this promising functionality broken. If I don't hear back from this group in a day or two, I'll email Bare Bones support. If I get any word from them, I'll relay it back here.
Cheers,
AJ
