Hanging up of svn and apache process while using username argument with svn command.

I found a reproductable hang in the using of username argument of svn
commands.

The problem can be reproduce in every part of the repository with an
1.2.0 client and a 1.1.2 client and with the svn update or svn commit
command (i didn't test other commands).

To create the hang i run :
"svn update --username=alexis" where the username is not the one with
which you was working on the working copy.
The command ask you for the password of the user and then hang.
When I kill the process, the working copy is left with every directory
locked.

I must kill the process to terminate the program on the server and
client side.

On the server side, the apache process doesn't end and keep using 100%
of the cpu.

I'm using :
db-4.3.28.NC
neon-0.24.7
apr-0.9.6
httpd-2.0.54
php-4.3.11
apr-util 0.9.6
subversion 1.2.0

I'm using an authentication file like this one :
[/]
*=rw
aTestUser=r

[/branches/dist1.2.2]
*=r
@distWriters=rw

[/trunk/tools/security]
*=
@distSecurity=rw

[/branches/dist1.2/tools/security]
*=
@security=rw

[/branches/dist1.2.2/tools/security]
*=
@distSecurity=rw

[groups]
security=alexis,aydon
distWriters=phi,aydon,noregress,calvin,jyp,alexis,boris,jmb,eric

I'm using ldap authentification system. I don't remember having those
problem with 1.1.2 server version but i'm not sure I use the username
argument in a command.

I have those error in the apache error log each time the process hang :
[Tue Jul 05 14:23:27 2005] [warn] [client 192.168.12.41] [23267]
auth_ldap authenticate: user alexis authentication failed; URI
/svn/trunk [ldap_simple_bind_s() to check user credentials
failed][Invalid credentials]
[Tue Jul 05 14:23:27 2005] [warn] [client 192.168.12.41] [23267]
auth_ldap authenticate: user alexis authentication failed; URI
/error/HTTP_UNAUTHORIZED.html.var [ldap_simple_bind_s() to check user
credentials failed][Invalid credentials]

Does any one could reproduce the problem ?

I have a problem with subversion.

To reproduce the problem you have to issue on a working copy :
"svn update --username=alexis" where the username is not the one with
which you was working on the working copy.
The command ask you for the password of the user and then hang.
When I kill the process, the working copy is left with every directory
locked.
