Slow work with shares mounted by pam_mount

[TiFix]

Libre Office (Tried different versions) very slowly opens documents located on a network share mounted with pam_mount utlity. In case if i mount the same resource using “mount-t cifs” command then documents open quickly.
The problem is observed only with libre office, other editors open documents quickly.
I’m use Debian-based distro. How to understand what the problem is?
Collected work logs using libreoffice7.0 --strace. Throughout the “freezing” of the libre office in the logs, messages like:

4130 12:58:55.413241 close(92) = -1 EBADF (Bad file descriptor)

And so on for a minute

[TiFix]

The following mount options solve this problem:

options=“user=%(USER),cruid=%(USERUID),dir_mode=0770,file_mode=0770,rw,iocharset=utf8,noperm,soft,nouser_xattr,vers=1.0”

“vers=1.0” pframeter needed only for Windows Server 2003 shares.
