cron not sending emails (SOLVED)

[Carlos Fernando Assis Paniago]

I Had a terrible week with freebsd. In monday I did an upgrade from 7.3 
to 8.1-prerelease in 3 machines, 2 of them worked normaly and one stop 
functioning, and without user (ldap) e cron is not sending emails. The 
log for cron is:

Jun 10 19:45:00 sol /usr/sbin/cron[80892]: (root) CMD (/usr/libexec/atrun)

The ldap stop working with the messages:

2010 17:16:31)

and in auth.log this log

Jun  7 19:22:17 sol login: pam_acct_mgmt(): error in service module


And until today after recompiling everithing from the ports to the 
system I cannot find the error.

Today I found this:

rigel# ldd  /usr/local/lib/nss_ldap.so.1
/usr/local/lib/nss_ldap.so.1:
         libldap-2.3.so.2 => /usr/local/lib/libldap-2.3.so.2 (0x800c00000)
         liblber-2.3.so.2 => /usr/local/lib/liblber-2.3.so.2 (0x800d37000)
         libsasl2.so.2 => /usr/local/lib/libsasl2.so.2 (0x800e45000)
         libkrb5.so.10 => /usr/lib/libkrb5.so.10 (0x800f5d000)
         libcom_err.so.5 => /usr/lib/libcom_err.so.5 (0x8010ca000)
         libgssapi_krb5.so.10 => /usr/lib/libgssapi_krb5.so.10 (0x8011cc000)
         libc.so.6 =>(unknow)
         libssl.so.6 => /usr/lib/libssl.so.6 (0x8012e6000)
         libcrypto.so.6 => /lib/libcrypto.so.6 (0x801438000)
         libgssapi.so.10 => /usr/lib/libgssapi.so.10 (0x8016d2000)
         libhx509.so.10 => /usr/lib/libhx509.so.10 (0x8017db000)
         libroken.so.10 => /usr/lib/libroken.so.10 (0x80191a000)
         libasn1.so.10 => /usr/lib/libasn1.so.10 (0x801a2b000)
         libcrypt.so.5 => /lib/libcrypt.so.5 (0x801baa000)

The problem was the libsasl2 (cyrus-sasl2) that was old. I found a lot 
of pages in google with this problem and no solution.
And I find it using the command "cd /usr/local/lib ; grep -R libc.so.6 
*". After the finding I compiled the module (cyrus-sals2) and everything 
comes back to normal.

The problem is that nss_ldap.so.1 dont say that the library is missing 
but point the error to the PAM modules.

Everyone that have this same problem try to find in the nss_ldap, 
pam_ldap etc, some reference to old libs.
