A few days ago my login got moved from one Windows domain to another. I've had to deal with several problems as a result of that. One particular problem is having with SVN. For some reason SVN is prompting me for a password on every single operation it tries to do.
This is tolerable in Eclipse (Subversive plugin), as I simply have to press Enter on the dialog each time, as it's preentered the name and password. However, it's worse from the command line. I can get it to work if I manually add "--password ..." to the command line. If I don't, the Cygwin Bash shell seems to get confused about how to handle the prompts. I have to use a non-Cygwin SVN. I never had to re-specify the password on every operation before the domain migration.
