## Symptoms

- * VPN Outage for all LDAP Authenticated Remote Access Users.
* Usernames and Passwords for the Users have been verified as correct.
* *vpnd.elg* Shows:   

  *\[ 8218\]\[1 Jan 2017\]\[HOSTNAME\] server = DC01, SDK Response \<code = 49, message = Invalid credentials , Error Message = 80090308: LdapErr: DSID-0C09042F, comment: AcceptSecurityContext error, data 773, v2580*

## Cause

The **Domain Administrator account** (configured in SmartDashboard for the LDAP Account Unit used to access the DC) has recently changed its password, or its password reset policy is currently enforcing a password change procedure.

**Code 49** tells us that the username/password is incorrect.

**Data 773** tells us that the user must reset password.

**This is not the VPN Client username/password.**

**It is the Domain Administrator account**that is referred to.
