When a user attempts to log in to the vSphere Web Client, authentication fails.

Users of a particular domain cannot log in to the vSphere Web Client. The following error message appears in the log: Error connecting to the identify source. For Active Directory domains, the following error appears in the log: Unable to create managed connection [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurity Context error, data 52e, vece].

When you configure an identity source to use Password as the authentication type, and the password changes for the administrator user whose credentials are associated with the identity source, authentication fails for users in that domain.


Select Administration > Sign-On and Discovery > Configuration, and click the Identity Sources tab.


Right-click the identity source and select Edit Identity Source.


Type the new password and click Test Connection.


If the connection is established successfully, clickOK.
