[](https://doc.eainfoport.cz/uploads/images/gallery/2022-03/question-mark-1.png)
### Question
I have connected the repository to the Infoportal. In Enterprise Architect I created a new root node (new model), but unfortunately in Infoportal the user with basic permissions cannot see it. How to solve this problem?
- - - - - -
### Answer
In version 7.x, the user is unfortunately forced to delete the repository and recreate it.
As of version 8.x, a button has been added to the repository edit for everyone, which will reset the permissions and thus create a default permission on the newly created model.
Users who own Medium Business Edition and above also have the option to manually set this default permission manually on behalf of the repository admin or model owner via the Permissions tab in the tree.# What happens if a user connects an EA repository to the infoportal and then migrates the database data?

[](https://doc.eainfoport.cz/uploads/images/gallery/2022-03/question-mark-1.png)
### Question
Why can't LDAP login/logout?
- - - - - -
### Answer
Since version 8.0.1.x, we have normalized Windows Authentication to .Net 6 libraries.
Windows user who is not in LDAP will not be able to log in. Only users authenticated against LDAP and without the ability to log out will automatically log in.
For non-LDAP login, the administrator will need to set the AutomaticLogin entry in the LDAP section of appsettings.json to false and restart Infoport. This will remove the automatic login option, but the Login Page will be able to authenticate a user who is not in LDAP, but only in the database.# What should I do if I have collations inconsistency in my database (MySQL)?
[](https://doc.eainfoport.cz/uploads/images/gallery/2022-03/question-mark-1.png)
### Question
What should I do if I have collations inconsistency in my database (MySQL)?
- - - - - -
### Answer
**The following applies only to MySQL :**
As of version 8.2, schema collation must be consistent with the collation of individual tables and columns or Infoport will not allow migration. The database admin must unify the collation on the schema.
To display collation on columns, use query:SELECT DISTINCT COLLATION\_NAMEFROM information\_schema.columns
WHERE TABLE\_SCHEMA = 'schemaName'ANDTABLE\_NAME <> '\_\_EfMigrationsHistory' AND COLLATION\_NAME IS NOT nullTo display collation on tables, use query:
SELECT DISTINCT TABLE\_COLLATION
FROM information\_schema.`TABLES`
WHERE TABLE\_SCHEMA = 'schemaName' ANDTABLE\_NAME <> '\_\_EfMigrationsHistory'To display the collation on the diagram, use query:
**SELECT** **TABLE\_NAME**, **COLUMN\_NAME**, COLLATION\_NAME
**FROM** information\_schema.**columns**
**WHERE** TABLE\_SCHEMA = 'schemaName'**AND** COLLATION\_NAME **IS** **NOT** **NULL****AND** **TABLE\_NAME** <> '\_\_EfMigrationsHistory'
**GROUP** **BY** **TABLE\_NAME**, **COLUMN\_NAME**, COLLATION\_NAMEPlease reunite the collation and restart Infoport.You can use the following scripts for unification: For each table:SELECTCONCAT('ALTER TABLE `', TABLE\_NAME, '` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4\_unicode\_ci;') AS'USE `DATABASE\_NAME`;'FROM INFORMATION\_SCHEMA.TABLES WHERE TABLE\_SCHEMA ='DATABASE\_NAME'AND TABLE\_TYPE LIKE'BASE TABLE'For each column:SELECTCONCAT('ALTER TABLE `', TABLE\_NAME, '` MODIFY COLUMN `', COLUMN\_NAME,'` ', DATA\_TYPE, IF(CHARACTER\_MAXIMUM\_LENGTH ISNULLOR DATA\_TYPE LIKE'longtext', '', CONCAT('(', CHARACTER\_MAXIMUM\_LENGTH, ')') ), ' COLLATE utf8mb4\_unicode\_ci;') AS'USE `DATABASE\_NAME`;'FROM INFORMATION\_SCHEMA.COLUMNS WHERE TABLE\_SCHEMA ='DATABASE\_NAME'AND (SELECT INFORMATION\_SCHEMA.TABLES.TABLE\_TYPE FROM INFORMATION\_SCHEMA.TABLES WHERE INFORMATION\_SCHEMA.TABLES.TABLE\_SCHEMA = INFORMATION\_SCHEMA.COLUMNS.TABLE\_SCHEMA AND INFORMATION\_SCHEMA.TABLES.TABLE\_NAME = INFORMATION\_SCHEMA.COLUMNS.TABLE\_NAME LIMIT 1) LIKE'BASE TABLE'AND DATA\_TYPE IN( 'char', 'varchar' )/\* includeothertypesifnecessary \*/Please contact the helpdesk for more information [https://www.dphelpdesk.cz/](https://www.dphelpdesk.cz/) . # What is the required EA schema to connect EA repository?

### Question:
What is the required EA schema to connect EA repository?
### Answer:
MySQL database server with a schema of at least EASchema\_1220\_MySQL.sql, our recommendation EASchema\_1558\_MySQL.sql. (Note: EASchema\_851\_MySQL.sql does not work).# Version 8.4.0.12 - Access to views
In version 8.4.0.12, a new permission for views (Views) is added. For users/groups with permissions on the tree, you must also add permissions on views, otherwise the view will not be displayed.
Version 8.4.1.1 there is no need to add settings. A user authorized to the repositories tree also has access to views.

### Question
Since version 8.5.0.8563 admin can't get into the repositories?
[](https://doc.eainfoport.cz/uploads/images/gallery/2022-12/image-1670942005795.png)
### Answer
Now, because of audit reasons, the admin (portal administrator) is not automatically assigned access to the repository. After clicking the arrow in the top left corner, he only sees the list of created repositories.
If necessary, it is necessary to set permissions to the required repositories via "Portal Management">"User Management">"User List".# InfoportLauncher can not install the version via "-Source file"

### Question
How are permissions applied to groups/users when using the "Direct Access URL" feature?
[](https://doc.eainfoport.cz/uploads/images/gallery/2022-12/image-1670942005795.png)
### Answer
The "direct access URL" functionality is designed for the very purpose of allowing anyone who has the link to get to the published link. That is why the link includes a generated security key. If you want to authenticate the reader, do not use this functionality, but use the "Copy url" functionality (careful, this is not the same as copying the link in the browser!)
This is used, for example, where authentication + authorization is handled in a different way (Confluence, Sharepoint, some documents, etc.) or if you simply need to make sure that (for example) everyone who clicks on the diagram actually gets to see it.
However, a diagram published in this way will only take the reader to the detail of the elements placed on the diagram, if they want to click further, for example via a hyperlink, it will already require a login.
A user can only create a url for direct access if he/she has rights to it.

### Question
[](https://doc.eainfoport.cz/uploads/images/gallery/2024-05/image-1715936143328.png)
How to set up SSL communication for connecting EAInforport and PostgreSQL database?
### Answer
The following procedure is verified on a PostgreSQL 13 and Infoport 8.7.x installation.
A detailed description of the database setup is provided directly in the current documentation [https://www.postgresql.org/docs/current/ssl-tcp.html ](https://www.postgresql.org/docs/current/ssl-tcp.html)which we recommend to study carefully. In addition, [https://methoddev.com/blog/postgresql-windows-encrypted-connection-ssl](https://methoddev.com/blog/postgresql-windows-encrypted-connection-ssl) provides a step-by-step procedure on how to configure the database in practice.
To verify that the communication is secure, it is advisable to use the following sql query that can be run on the database:
SELECT application\_name, datname, usename, ssl, client\_addr
FROM pg\_stat\_ssl
INNER JOIN pg\_stat\_activity ON pg\_stat\_ssl.pid = pg\_stat\_activity.pid;
The result will show if the session (a specific application connection - e.g. EAInfoport) is secured by ssl. It is recommended to check this both before starting any changes to the settings and after they are completed.
EAInfoport settings are (for now - later will be part of Configuration Manager) done using the appsettings.json configuration file. Here you need to add the value "InfoportConnection\_Npgsql" with ";ApplicationName=Infoport;SSL Mode=VerifyCA". This setting means that EAInfoport will require an ssl connection to the database, and will check that a trusted certificate exists.
***Note:*** if the db server is set to require ssl (=reject connection without ssl) but the connection string of EAInfoport is set to ";SSL Mode=Disable", the EAInfoport log will show a message like "28000: pg\_hba.conf rejects connection for host "x.x.x", user "xx", database "xx", SSL off".
- - - - - -
EAInfoport version 7.x has not been developed or tested for ssl connections, but the following can be tested:
Since version 6 (.NET - not the database) the parameter variations for ssl have been changed (see also Security and Encryption | Npgsql Documentation)
Npgsql v6.0+:
Disable
Allow
Prefer (default)
Require
VerifyCA
VerifyFull
Npgsql pre-v6.0:
Disable (default)
Prefer
Require
For .NET version 2 (= for EAInfoport 7.x) it is possible to try ';SSL Mode=Prefer' as a parameter or add that I trust the certificate, i.e. ";SSL Mode=Prefer;Trust Server Certificate=true"
The last option is to replace Prefer with Require# After installing EA Infoport 8.7.0.8956, the icons for creating access keys (permalinks) are not displayed
In EaIfoport there is a new option to set users to "Public Key Publication Permissions".

How to change the order of artifacts and operations so that they are not sorted alphabetically?
[](https://doc.eainfoport.cz/uploads/images/gallery/2024-05/image-1715936143328.png)
### Answer
If you want EaInfoport to follow the order of attributes and operations as you define them (manually), it is necessary to disable ordering in EA, see below.

### Question
What if you get the following error when installing version 8.8.x?
Could not load file or assembly 'Serilog.Filters.Expressions, Version=2.1.0.0, ...
[](https://doc.eainfoport.cz/uploads/images/gallery/2022-03/question-mark-1.png)
### Answer
The error may occur when running version 8.8.x if version 7.x.x was once installed on the server.
You need to find the file "Serilog.Filters.Expressions.dll" in Infoport version 8.8.x and delete it.# Error [ERR] Email 'xxx.yyy@xxxx.cz' is already taken
What should be the correct administrator action if there is an entry in the log
\[ERR\] Email 'xxx.yyy@xxxx.cz' is already taken out of sync with AD?
[](https://doc.eainfoport.cz/uploads/images/gallery/2025-03/image-1743169580247.png)
The administrator should make sure that the email is entered correctly and is not duplicated (in Active Directory)
Error occurs if the user is manually modified e.g. changing the username in Infoport.
It is recommended to track the change and edit it in Activ Directory or Infoport.
Alternatively, the user can be deleted in the Infoport database, after synchronization with AD, the user is re-established in Infoport in the correct way.# [ERR] User 'xxx.yyy@xxxx.cz' had once existed and was deleted from the portal
What does it mean when the following error pops up?
\[ERR\] User 'xxx.yyy@xxxx.cz' had once existed and was deleted from the portal. If you need to restore him, contact the portal administrator please.
[](https://doc.eainfoport.cz/uploads/images/gallery/2025-03/image-1743169580247.png)
The error occurs if the user is deleted only in the Infoport and Active Directory is trying to synchronize the user.
We recommend deleting the user directly in the Infoport database.# Micrsosoft database (sql sever 2014 and older) - Microsoft.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '$'.
You have a Micrsosoft database (sql sever 2014 and older) and EaInfoport does not work correctly since version 8.8.0.9195 or you get the error message Microsoft.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '$'. ?

When you try to display the diagram (image), two messages are displayed in turn. The first informative "Diagram is being regenerated" followed by the second error "System error"
[](https://doc.eainfoport.cz/uploads/images/gallery/2025-03/image-1743163781636.png)
If we look in the DevTool browser (F12) we can see the Console message that there are no rights to read the .png file (where the requested image is).
Furthermore, the Infoport log shows an entry about the inability to generate the image (typically reported by EA.Interop.dll / DCOM)
One of the causes may be a problem with access to the cache files, when something (failure, downtime, migration, etc.) causes the rights to the file caching the diagrams to be lost or locked by some process.
The files are available for reading (that's why most of them are displayed in Infoport), but as soon as they need to be regenerated (new diagram, change on diagram, etc.) it is not possible and the user gets an error in the browser. This is because when the Sparx DCOM is called, it failed to update the file on disk (in the cache).
The solution is to delete the directories that make up the \\wwwroot\\cache\\\* cache.# One user cannot log in to Infoport
