Hello,

we use dovecot v1.1.16 on two servers with Solaris 9. This week both suddenly stopped authenticating users. The first server was startet on Jun 2 and ran until Jun 18 and the other startet on Jun 3 and failed on Jun 15. Both generated then lots of error messages, three for every user that attemps to login, looking like that:

Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 401707 user.error] open_module: /usr/lib/security/pam_unix_account.so.1 failed: ld.so.1: dovecot-auth: fatal: /usr/lib/security/pam_unix_account.so.1: open failed: No such file or directory Jun 15 08:35:23 minerva dovecot-auth[20831]: [ID 487707 user.error] load_modules: can not open module /usr/lib/security/pam_unix_account.so.1 Jun 15 08:35:23 minerva dovecot: [ID 107833 local0.error] auth-worker(default): pam(gp1071,134.176.2.89): pam_acct_mgmt() failed: Dlopen failure

The file /usr/lib/security/pam_unix_account.so.1 was still there and had not been changed.

Until these events there have been on both servers circa 1.600.000 logins.

After a restart dovecot did work again.

The configuration is:

ulimit -n 8192

/opt/local/sbin/dovecot -n

1.1.16: /opt/local/etc/dovecot.conf
