What does error code 49 mean?

When applications or services fail to authenticate users or service accounts against an LDAP directory server, the system logs show an authentication failure with the message LDAP: error code 49, along with diagnostic codes.

• LDAP: error code 49: This is the generic LDAP error for invalid credentials.
• 80090308: This is a Windows-specific hexadecimal error code that often accompanies LDAP: error 49 in AD environments.
• data 52e: This sub-code helps us identify the specific reason for the authentication failure.
