pam_ldap - trouble understanding the do_authentication function

[vidya chandrasekaran <sc_vidya@xxxxxxxxx>]

Hi,

I have been reading the source of pam_ldap(pam_ldap-180)

From what i understand of the authentication logic,

1. The username being authenticated is searched in the ldap directory to get the userdn (_get_user_info  ()), following which
2. a simple bind is attempted. (_connect_as_user)

What escapes me is this, why a _connect_anonymously() call follwing step 2

Any pointer will be much appreciated.

Thanks
Vidya
