.Added an option to manually control the maximum offline timeout The `offline_timeout` period determines the time incrementation between attempts by SSSD to go back online. Previously, the maximum possible value for this interval was hardcoded to 3600 seconds, which was adequate for general usage but resulted in issues in fast or slow changing environments. This update adds the `offline_timeout_max` option to manually control the maximum length of each interval, allowing you more flexibility to track the server behavior in SSSD. Note that you should set this value in correlation to the `offline_timeout` parameter value. A value of 0 disables the incrementing behavior.

Description Alexey Tikhonov 2020-10-01 11:23:30 UTC 
The offline_timeout period determines the minimum time between attempts of a data provider to go back online, if it is offline due to eg. unreachable servers. Each time this check fails there is a backoff factor applied meaning there can be up to 60 minutes between these attempts.

We need to introduce the offline_timeout_max option which allows the the maximum period between attempts to be defined in the configuration, instead of the default 60 minutes; therefore providing more flexibility.

Setting offline_timeout_max to 0 will disable the backoff functionality.

Comment 15 Madhuri 2021-01-12 07:35:10 UTC 
[root@ci-vm-10-0-155-17 sssd]# rpm -qa sssd
sssd-2.4.0-5.el8.x86_64

From man page,

       offline_timeout (integer)
           When SSSD switches to offline mode the amount of time before it tries to go back online will increase based upon the time spent disconnected. This value is
           in seconds and calculated by the following:

           offline_timeout + random_offset

           The random offset value is from 0 to 30. After each unsuccessful attempt to go online, the new interval is recalculated by the following:

           new_interval = (old_interval * 2) + random_offset

           Note that the maximum length of each interval is defined by offline_timeout_max, which defaults to one hour. If the calculated length of new_interval is
           greater than offline_timeout_max, it will be forced to the offline_timeout_max value.

           Default: 60

       offline_timeout_max (integer)
           Controls by how much the time between attempts to go online can be incremented following unsuccessful attempts to go online.

           A value of 0 disables the incrementing behaviour.

           The value of this parameter should be set in correlation to offline_timeout parameter value.

           With offline_timeout set to 60 (default value) there is no point in setting offlinet_timeout_max to less than 120 as it will saturate instantly. General rule
           here should be to set offline_timeout_max to at least 4 times offline_timeout.

           Although a value between 0 and offline_timeout may be specified, it has the effect of overriding the offline_timeout value so is of little use.

           Default: 3600

Verification steps:

1. Configure ldap server with sssd client
2. Make server offline
3. Add offline_timeout_max with different values
4. Restart sssd after clearning the logs


case 1:
offline_timeout_max = 190
