For how long are LDAP user credentials cached on the ProxySG?

LDAP user credentials are cached on the ProxySG for 15 minutes to improve the efficiency of user authentication. Caching credentials helps reduce the number of repeated queries sent to the LDAP server, which can enhance performance and reduce the load on the server itself. This time frame strikes a balance between keeping credentials fresh enough for security purposes while providing sufficient caching to optimize response times for user access. Therefore, the 15-minute cache duration is implemented to ensure efficient access while maintaining security integrity. This mechanism enables quicker access for repeat users without compromising on the timely validation of credentials against the LDAP server.
