Apmd crashes when iRule command "ACCESS::policy evaluate"is used to evaluate the access policy in clientless mode.
Apmd crashes or restarts.
This occurs when following conditions are met: - iRule command "ACCESS::policy evaluate" is used to evaluate the access policy. - If LDAP/AD query agent is configured in access policy to fetch many attributes. If the data is more than 64K, apmd will hit segfault (SIGSEGV) when trying to copy them.
Limit the number of attributes in Ldap/AD query agents. Apmd doesn't crash if the total data are less than 64K.
Access Sessions with large amounts of session variable data are now created properly when called from the "ACCESS::policy evaluate" iRule command.
