Alan, many thanks ! although it took me some time, "simple Math" isn't one of my real strenghts and I still haven't fully understood ;), I worked out now to disconnect at 04:00 CEST / 03:00 CET (Timestamp is GMT, I should have remembered):

Math. See rlm_expr. To disconnect people at midnight every day, calculate the time left until the next midnight. Session-Timeout := `%{expr: ((%l + 86399) %% 86400) - %l}` To disconnect people at 3:30... it gets a little more complicated. Time since the previous midnight: %l - (%l %% 86400) Time since the previous 3:30am: (%l - 12600) - ((%l - 12600) %% 86400) Time until the next 3:30 am is one day, less the time since the previous 3:30 am. 86400 - (%l - 12600) - ((%l - 12600) %% 86400) Or, 86400 + 12600 + ((%l - 12600) %% 86400) - %l. e.g. "one day, plus time until 3:30, plus the time of the previous day it was 3:30, and subtract from that the current time". The complicated nature of the calculation is due to the fact that when people log in at 02:30, you want to disconnect them at 03:30, and when they log in at 04:30, to disconnect at the next 03:30. You can't do comparisons in rlm_expr, so it's easier to make the calculations a little more complex. Alan DeKok. - List info/subscribe/unsubscribe?
