When updating LDAP servers, it is crucial to take measures to ensure the continuity of senhasegura authentication and minimize any possible interruption of access to the application. If the LDAP service is stopped, senhasegura users who use this service will not be able to log in, limiting access only to users authenticated through the local provider.
