Disable multiple ssh logins for an OS user in Solaris
Hi folks,
I am fairly a beginner when it comes to Solaris OS administration, but part of my job somehow has scope to provide L1-level of OS administration over a few solaris servers.
Now, we have a requirement to limit the number of simultaneous ssh logins/sessions to the server, sort of similar to a windows server where an OS windows account can only be used one at a time, so if another colleague logged in to that same windows server, my current RDP session will be cut off.
Is there any way to do the same for a solaris server? My servers are on SunOS 5.11 11.3 sun4v sparc.
I've done some googling and I see the files "/etc/limits" and "/etc/security/limits.conf" being mentioned but I don't have those in my server.
Any input from the community will be very much appreciated.

Goal: To disable a Solaris user, after that user was inactive for X days.

xunmapsubwindows
XUnmapWindow(3) XLIB FUNCTIONS XUnmapWindow(3)
NAME
XUnmapWindow, XUnmapSubwindows - unmap windows
SYNTAX
int XUnmapWindow(Display *display, Window w);
int XUnmapSubwindows(Display *display, Window w);
ARGUMENTS
display Specifies the connection to the X server.
w Specifies the window.
DESCRIPTION
The XUnmapWindow function unmaps the specified window and causes the X server to generate an UnmapNotify event. If the specified window is
already unmapped, XUnmapWindow has no effect. Normal exposure processing on formerly obscured windows is performed. Any child window will
no longer be visible until another map call is made on the parent. In other words, the subwindows are still mapped but are not visible
until the parent is mapped. Unmapping a window will generate Expose events on windows that were formerly obscured by it.
XUnmapWindow can generate a BadWindow error.
The XUnmapSubwindows function unmaps all subwindows for the specified window in bottom-to-top stacking order. It causes the X server to
generate an UnmapNotify event on each subwindow and Expose events on formerly obscured windows. Using this function is much more efficient
than unmapping multiple windows one at a time because the server needs to perform much of the work only once, for all of the windows,
rather than for each window.
XUnmapSubwindows can generate a BadWindow error.
DIAGNOSTICS
BadWindow A value for a Window argument does not name a defined Window.
