When calling unbind_ldap_connection() if a sasl connection is
|
|
|
4d476f |
being used then autofs_sasl_unbind() should be called and not
|
|
|
4d476f |
ldap_unbind_ext(), otherwise the ldap connection release code
|
|
|
4d476f |
could be called twice.
|
|
|
4d476f |
|
|
|
4d476f |
So, in unbind_ldap_connection() check if a sasl connection is in
|
|
|
4d476f |
use and unbind it if it is otherwise call ldap_unbind_ext() to
|
|
|
4d476f |
release the ldap connection.
