Can't get LDAP Auth working

FYI: I have two databases:

1. ox6_database (created by me and used in ox setup as parameter for initconfigdb)
2. ox6_database_6 (created automatically by OX)

FYI: These are my contexts

# /opt/open-xchange/sbin/listcontext -A oxadminmaster -P verysecretpasswd
cid fid fname       enabled qmax qused name lmappings
  1   3 1_ctx_store true    1024     0 1    defaultcontext

I got a hint from cutmasta to change the context name to "defaultcontext" (I did not give a context name during installation using the -N parameter). So this is what I did to change the context name:

# /opt/open-xchange/sbin/changecontext -A oxadminmaster -P verysecretpasswd -c 1 -N defaultcontext -L defaultcontext

Now I have:

# /opt/open-xchange/sbin/listcontext -A oxadminmaster -P verysecretpasswd
cid fid fname       enabled qmax qused name           lmappings
  1   3 1_ctx_store true    1024     0 defaultcontext defaultcontext

Hi everybody,

I installed OX6 CE on Ubuntu Hardy Server and so far no problems, OX6 starts up and I can see the login screen. However, I installed the LDAP Auth plugin and I can see OX6 contacting LDAP in the LDAP-Logs, yet I get a "Login incorrect" message from OX6...

For further details please see also my posts here.

I took a look at the source code of the LDAP Auth plugin and saw that the error message I get is thrown when an InvalidNameException (?) or an AuthenticationException accours, but no loggin there...

Username and/or passwort are definetly correct I typed it in slow motion...

Any help (german/english) very welcome!

Regards,
Florian
