[CR #430808] When using LDAP User Authentification on certain versions of Linux AS 3.0, and where simultaneous LDAPUA connections are occurring on an engine, a segment violation may occur with the message “infected with 11” in the Adaptive Server Enterprise error log. The error may cause the Adaptive Server to shut down.
Workaround: Reduce the value of LDAPUA attribute max_ldapua_native_threads to 1 per engine:
sp_ldapadmin 'set_max_ldapua_native_threads', '1'
This reduction in the LDAPUA attribute avoids concurrent connections to the LDAP server during authentification.
