Autocomplete recipients when composing a message shows garbage

[Aierk]

Hi.

I just finish instaling gitorious (git cloned today) + Ldap in a fresh
debian squeeze server. Ldap Auth works fine but when i try to compose
a message the autocomplete only shows "###". Then, when you select one
of the "#" shows something like this "#<User:0x7083688>".

Here's my authentication.yml just in case

production:
disable_default: true
methods:
- adapter: Gitorious::Authentication::LDAPAuthentication
host: xxx.cl
port: 389
base_dn: ou=cuentas,ou=valparaiso,ou=alumnos,c=cl
login_attribute: uid
distinguished_name_template:
"uid={},ou=cuentas,ou=valparaiso,ou=alumnos,c=cl"
attribute_mapping:
cn: fullname
mail: email
encryption: none

Anyone can help me?
