Nextcloud version (eg, 12.0.2): 12.0.3
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04.3

PHP version (eg, 7.1): 7.0
In NextCloud I need to implement authorization of users stored in external Postgre-database. The algorithm for hashing passwords in that DB:
Hash = SHA1 (salt + SHA1 (password));
the salt is stored in the same database.
“Native” (MySQL) authorization should remain.
Any ideas/suggestions how it can be done?
