I installed Mintty fresh this morning on a new laptop that connects to a work network over a VPN. I noticed that when I am connected to the VPN, mintty takes ages to open. After some research, I found that I could start mintty with strace to see what is going on. When i did that, I saw loads of messages about ldap lookups. The first is my account:

767294  822875 [ldap_init] mintty 7860 cygthread::stub: thread 'ldap_init', id 0x5F8, stack_ptr 0x29FCCE0
4701686 5524561 [main] mintty 7860 pwdgrp::fetch_account_from_windows: line: <jv:*:1066912:1049089:U-<DOMAIN NAME>\jv,S-1-5-21-1669953581-1272186783-1231754661-18336:
/home/jv:/bin/bash>

Then I see tons of errors around this, which looks like it is looking up every group in my Active Directory domain:

385771 23061964 [main] mintty 7860 pwdgrp::fetch_account_from_windows: line: <NA Wireless:S-1-5-21-1669953581-1272186783-1231754661-11202:1059778:>

889 50026168 [main] mintty 7860 geterrno_from_win_error: windows error 234
errno 122

Over and over with the windows error 234 and errno 122.

I know this is domain related because I can open mintty when not connected to the VPN and it works almost immediately.

Any suggestions on what I should do to resolve this issue?

In the /etc/nsswitch.conf try uncommenting the group: line and removing the db leaving just files:

group: files

  • This makes it faster, but then i see the following, which i think would cause permission problems right? /usr/bin/id: cannot find name for group ID 1049089 – Jason V Mar 03 '15 at 18:53
