SYMPTOMS
When you try to establish a Lightweight Directory Access Protocol (LDAP) connection to an LDAP server over a Secure Sockets Layer (SSL) channel, the connection may be unsuccessful, and the SEC_E_WRONG_PRINCIPAL error may be returned.



CAUSE
This problem may occur if all the following conditions are true:
 * An alias (CNAME resource record) is mapped to a host (A resource record) in DNS, and the host is the LDAP server.
 * The certificate for the LDAP server is under the alias name.
 * LDAP clients use the alias name to connect to the LDAP server.
