SVN Update on a symfony project

Hi all

I am new to subversion and that is why i need to ask what is the issue i am getting

so basically I am trying to run an SVN Update for my working branch

-bash-3.2$ svn info Path: . URL: http://svn.xxxx.xx.xx/branches/staging
Repository Root: http://svn.xxxx.xx.xx
Repository UUID: 9298bc80-5b70-4429-9a3b-f3b66138d9f1
Revision: 43
Node Kind: directory
Schedule: normal
Last Changed Author: xxxx
Last Changed Rev: 38
Last Changed Date: 2010-05-05 19:25:18 +0100 (Wed, 05 May 2010)

after the svn update command it is asking me for a password

-bash-3.2$ svn update
Authentication realm: http://svn.xxxx.xx.xx:80 SVN
Password for 'xxxx':

So I am giving my password and then it asked me for this

Authentication realm: http://svn.xxxx.xx.xx:80 SVN
Username: (here i am typing the same username xxxx)
Password for 'xxxx': here the same password

and then i got this:

svn: PROPFIND request failed on '/branches/staging'
svn: PROPFIND of '/branches/staging': authorization failed (http://svn.xxxx.xx.xx)

I don't know why it asks me for another username and password if at first place asked me to confirm my password

please help with that cause I can't run my SVN update

thanks in advance
