Hi,

Now I meet a strange thing. I can clog into Coda, but I can NOT take any operations.

The operations are following :
1) clog    
    Result: OK!
2) ctokens
    Result:
    Token held by the Cache Manage:
    Local uid: 503
    Coda user id: 503
    Expiration time: Sat Aug 28 12:13:08 1999
3) cfs la /coda
    Result:
    System:Administrators    rlidwka
    System:AnyUser        rl
4) ctokens
    Result:
    Token held by the Cache Manage:
    Local uid: 503
    Not Authenticated
#this is very strange, I don't know why.
5) cfs whereis /coda
    Result:
    langchao7.cs.tsinghua.edu.cn

Pls give me some advices. Thanks!
