To let you control operating system and third-party processes, Privileged Identity Manager lets you automatically make calls to UNIX exits when loading the Privileged Identity Manager kernel extension.
When you run
SEOS_load
, Privileged Identity Manager performs the following actions:- Looks for programs in the following directory:ACInstallDir/exits/LOAD
- Selects all the programs that have file names of the following format:
WhereSEOS_load_string.alwaysstringcan be any descriptive strings. - Executes, in lexicographical order, each file it found in the directoryACInstallDir/exits/LOAD:
Each file is executed with theSEOS_load_string.always -pre-preparameter so that you can write your exits to detect the parameter and perform the actions required before the kernel is loaded.If the exit returns a nonzero value, Privileged Identity Manager kills the exit process, displays an error message, and aborts the kernel loading. - Loads the kernel (SEOS_syscall).
- Executes, in lexicographical order, each file it found in the directoryACInstallDir/exits/LOAD:
Each file is executed with theSEOS_load_string.always -post-postparameter so that you can write your exits to detect the parameter and perform the actions required after the kernel is loaded.If the exit returns a nonzero value, Privileged Identity Manager kills the exit process and displays an error message. Having already been loaded, the Privileged Identity Manager kernel remains loaded.
