Difficulty checking out svn project with alternate username

I'm trying to check out a project from a sc开发者_JAVA技巧hool server, but it attempts to use my computer login name instead of my server login name, so it fails.

my commands:

svn checkout svn+ssh://[server name and stuff]/[school login name]

and it says:

[computer login]@[server name]'s password:

which doesn't exist.

I attempted to use the --username parameter:

svn checkout --username [school login] svn+ssh://[server name and stuff]/[school login name]

but it requests the same password for the same nonexistent user. What am I doing wrong with my checkout command?

Try

svn checkout svn+ssh://[school login name]@[server name]/[svn path]

Two things:

(1) clear out all client credentials cache http://chestofbooks.com/computers/revision-control/subversion-svn/Client-Credentials-Caching-Serverconfig-Netmodel-Credcache.html

(2) Is the school's server misconfigured (or intentionally configured that way)? For example, it may be hardwired to require you to connect from a school computer.
