In order to get help on APIs, you can consult the documentation directly from your instance. To do this, in **`setup`** > **`general`** > **`API`** change the option to **`Yes`** to **`enable API Rest`**. The **`online API documentation`** option will appear. If you get an error message when you click on the documentation, click on **`full access from localhost`** and delete the IPs (or enter the IP of the workstation you are on) in the start and end of IPv4 address range fields. *** ### Do you have a password policy? Yes, for internal accounts only. As external accounts (LDAP, SSO, etc.) depend on a dedicated server, this policy cannot be applied to these accounts. It is possible to request that the password : * requires at least one number, * requires at least one lower case letter, * requires at least one symbol, * be of a minimum length (configurable length), * expires after a set period of time, * is deactivated if the password has not been changed for a certain period of time (configurable time limit), It is also possible to request that an expiry notification be sent to users. *** ### How to disable password reset by e-mail? To disable password reset by e-mail, you need to deactivate the **`Password forget`** notification (**`Setup`** > **`Notifications`** > **`Notifications`**). *** ### Can I increase the password reset time by one day? When you request a password reset from GLPI, you have 24 hours to carry out the reset. This time cannot be changed. If the 24 hours are exceeded, a new request must be made. *** ### How do I put GLPI into maintenance mode? If you have operations to perform that require GLPI to be put into maintenance mode, it is possible to do this in 2 ways: * In CLI (on premise only): in the glpi folder run **`php bin/console maintenance:enable`** (or **`php bin/console maintenance:disable`** to deactivate it) * In WebUI: in the **`setup`** > **`general`** menu **`system`** tab {% hint style="success" %} To override maintenance mode, you can access GLPI by adding **`?skipMaintenance=1`** (**) {% endhint %} *** ### How do I purge the GLPI history? In order not to overload the GLPI database, it is possible to purge the history of certain items: * general * software * financial and administrative information * users * components * all sections (purge all history entries) By default, the "keep all" option is selected. It is possible to keep the history for between 1 and 120 months, either per section or for the whole. {% hint style="info" %} History refers to the **`historical`** tab of a GLPI object. {% endhint %} *** ### What are locks used for? Locks are used to prevent certain information from being modified. {% hint style="success" %} You don't want the user field to be modified during automatic inventory feedback. {% endhint %} In this case, you need to activate the locks in **`Setup`** > **`General`** > **`General setup`**. Select U**`se locks`** and select the **`profile to be used when locking items`** and the **`types of object to lock`**. To lock a field, simply change it manually. Only the profile you have set up will be able to lock and unlock fields. To unlock them, go to the **`lock`** field of the item in question. A padlock ![Alt text](/files/hAJJxPWKSfwgiQAMFmJR) will appear when information is locked. *** ### Is it possible to set up working days for support? Yes, in **`Setup`** > **`General`** tab **`Assistance`** you can set up working days in the **`Planning work days`** field. *** ### How do I change my GLPI theme? There are several ways to change the theme: * For individual use: go to **`user settings`** (top right) then in the **`personalization`** tab you can choose the **`color palette`** that suits you. * For a global setting: go to **`setup`** > **`general`** > **`default values`**. You can choose the colour palette that suits you and will be applied to all users. You can also modify the CSS by entity. Go to **`administration`** > **`entities`**, select the entity you want, then **`UI customization`**. Indicate **`Yes`** in the **`enable CSS customization`** field and paste your CSS code in the dedicated area. *** ### Can I customise my instance's logo and theme? You can do this by downloading the **`Branding`** plugin (available on Cloud instances or with a "basic" subscription). Custom palette is available on GLPI 11 only. *** ### How do I assign a default language for all users? To change the default language, go to **`Setup`** > **`General`** > **`Default values`**. A **`default language`** field is available in the **`personalization`** section. This change is valid for all users. {% hint style="info" %} Users will still be able to change their language if they wish from their profile. {% endhint %} *** ### How do I retrieve my instance's UUID? Valid for on-premise instances only: In **`Setup`** > **`General`** click on **`See what would be sent`**. This is the 1st value that will appear: ``` "glpi": { "uuid": "hQ6ZuLpydjmaTuUCqnaqE6tTdsksio84sdfV8Kb1", "version": "10.0.18", } ``` *** ### How can I increase the number of search results per page? In **`Setup`** > **`General`** > **`General setup`**, adjust the **`Default search results limit (page)`** as desired. *** ### How can I deactivate the global search? In **`Setup`**> **`General`** > **`General configuration`**, put **`No`** to **`Global search`**. *** ### Can I activate/deactivate the option to **"remember me"\`**? In **`Setup`**> **`General`** > **`General configuration`**, at the bottom of the screen, click on deactivate or indicate in days the possible retention of the identifier. *** ### Can I configure closing days? It is possible to configure closing days (public holidays) from **`Setup`**> **`Titles`**, enter **`Closing`** and click on **`Closing periods`**. A procedure is [available](/tutorials/readme-1/calendar.md) to help you set them up. *** ### Can I increase the password reset time to one day? When you request a password reset from GLPI, you have 24 hours to reset your password. This time cannot be changed. If the 24 hours are exceeded, a new request must be made. A procedure is [available](/tutorials/readme-1/calendar.md) to help you set them up. *** ### Can we synchronize a calendar with GLPI? GLPI integrates a CalDAV server, which allows sharing of a GLPI calendar externally. It is also possible to modify it from both places. It's native via the link I provided previously. * To do this, go to **`Assistance`** > **`Planning`** * Click on * Then click on **`Copy CalDAV URL to clipboard`** * Paste this link into your email tool

Copying a link from an external email to GLPI (Outlook calendar type) is not native. You must use a third-party tool (outside the scope of Teclib) such as . *** ### How can I avoid importing duplicates into GLPI? If you don't want 2 items to have the same serial number, or 2 users to have the same ID, field uniqueness will help you avoid these duplicates. To configure it, you can follow this [procedure](/tutorials/readme-1/field_unicity.md). *** ### What types of documents/extentions can be uploaded to GLPI? From **`Setup`** > **`Dropdowns`** > **`Document types`** you can manage the types of documents authorised to be uploaded to GLPI:
